It can identify whether the stone is natural or laboratory-grown, record its measurements and document characteristics that affect its appearance, marketability and resale value.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0edbf99b\">Before selling, you should verify that the report exists in the issuing laboratory\u2019s official database. You must then establish that the physical diamond is the same stone described in that record.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3936ddde\">These are separate checks. A genuine report number proves that a laboratory record exists. It does not prove that the ring or loose stone in front of you matches that report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6a89af5a\">Shape, measurements, carat weight, clarity characteristics and any laser inscription can help connect the document with the diamond. Physical inspection is also needed to confirm that the stone has not been chipped, repolished, recut or treated since grading.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-c6bb5332\"><strong>Quick Answer: How Do You Check a Diamond Certificate?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8dbacd8a\">Find the issuing laboratory and unique report number on the document. Enter that number directly into the laboratory\u2019s official report-verification website and compare the returned information with the paper or digital report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-92580da0\">Check the diamond\u2019s natural or laboratory-grown description, shape, carat weight, measurements, colour, clarity, cut information and grading date. Any discrepancy should be investigated.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3020f2e7\">The physical diamond must then be matched to the record. A professional can inspect the laser inscription, measurements and clarity characteristics.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c365bed5\">Do not rely only on a QR code, screenshot or report number. An authentic report can still be presented with the wrong diamond.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-32427d07\"><strong>Diamond Certificate vs Diamond Grading Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e19d773a\">People commonly ask how to read a diamond certificate, but \u201cgrading report\u201d is usually the more accurate term.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8fb5835d\">A grading report records findings from a laboratory examination. Depending on the service, it may describe the diamond\u2019s origin, weight, quality characteristics, measurements, finish, fluorescence and known treatments.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7266c961\">It is not generally a guarantee of future value. It does not require a buyer to pay a specific amount, and it does not prove ownership.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-68daaa9c\">An insurance appraisal, purchase invoice or jeweller\u2019s valuation serves a different purpose. Those documents may contain a monetary figure, but they do not necessarily provide an independent laboratory grade.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-27d29294\"><strong>Begin by Identifying the Issuing Laboratory<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6bd48e54\">The report should clearly state which organisation examined the diamond. GIA, IGI and HRD Antwerp are examples of laboratories whose reports are commonly encountered in international diamond markets.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-349bceda\">Check the exact name and official domain rather than trusting a similar-looking logo. Fraudulent documents can imitate laboratory branding.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ee7711b9\">Use the laboratory\u2019s official website to access its report-check service. Type the address yourself or reach it through a trusted search result instead of depending exclusively on a QR code printed on an unfamiliar document.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a218d6a3\">Different laboratories use different terminology and formats. Read the scale and explanations printed on the report rather than assuming that every abbreviation has the same meaning.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7ec039ad\">Our separate guide compares<a href=\"https:\/\/sothisdiamonds.com\/nl\/gia-vs-igi-vs-hrd-diamond-reports\/\"> GIA, IGI and HRD diamond reports<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-e47ce2a1\"><strong>Identify the Exact Report Type<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a978cb9c\">A laboratory may offer several document types. A full natural-diamond grading report, dossier, digital report, jewellery report, coloured-diamond report and laboratory-grown assessment do not necessarily contain the same information.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bc8757bb\">Some reports contain a detailed clarity plot. Compact formats may not. Some services include a laser inscription, while others make it optional.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-11776075\">A loose-diamond report can normally provide more precise weight and measurements because the entire stone is accessible. A jewellery report may describe a mounted item within the physical limitations created by its setting.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6857d656\">Understanding the report type prevents you from treating an omitted field as evidence that the document is incomplete or false.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-47bfdbd7\"><strong>How to Read the Main Fields on a Diamond Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-045d29fa\">Although layouts differ, these are the principal fields likely to affect identification and resale assessment.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Report field<\/strong><\/td><td><strong>What it means<\/strong><\/td><td><strong>What to check before selling<\/strong><\/td><\/tr><tr><td>Rapportnummer<\/td><td>Unique reference assigned by the laboratory<\/td><td>Confirm it through the laboratory\u2019s official database<\/td><\/tr><tr><td>Report date<\/td><td>Date the diamond was examined<\/td><td>Consider whether damage, treatment or recutting occurred later<\/td><\/tr><tr><td>Description or origin<\/td><td>States whether the diamond is natural or laboratory-grown<\/td><td>Do not confuse growth origin with geographic mine origin<\/td><\/tr><tr><td>Vorm en slijpstijl<\/td><td>The outline and facet arrangement<\/td><td>Confirm the physical diamond has the same shape<\/td><\/tr><tr><td>Metingen<\/td><td>Dimensions recorded in millimetres<\/td><td>Compare with professional measurements of the stone<\/td><\/tr><tr><td>Karaatgewicht<\/td><td>Exact weight of the loose diamond<\/td><td>Mounted stones cannot normally be weighed precisely without removal<\/td><\/tr><tr><td>Kleurgradatie<\/td><td>Position on the applicable colour scale<\/td><td>Check the laboratory, scale and whether the colour is natural or treated<\/td><\/tr><tr><td>Zuiverheidsgradatie<\/td><td>Assessment of inclusions and blemishes<\/td><td>Review the plot and comments where available<\/td><\/tr><tr><td>Zuiverheid<\/td><td>Overall cut assessment where applicable<\/td><td>Confirm whether the shape is eligible for that grading system<\/td><\/tr><tr><td>Polijsting en symmetrie<\/td><td>Quality of facet surfaces and alignment<\/td><td>Check for later wear, damage or repolishing<\/td><\/tr><tr><td>Fluorescentie<\/td><td>Reaction to long-wave ultraviolet light<\/td><td>Consider intensity, colour and the diamond\u2019s actual transparency<\/td><\/tr><tr><td>Comments and treatments<\/td><td>Additional information not captured by the headline grades<\/td><td>Read every comment before estimating value<\/td><\/tr><tr><td>Laserinscriptie<\/td><td>Microscopic number or wording on the girdle<\/td><td>Have it compared with the report under magnification<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c594eaaa\">The report must be interpreted as one connected description. No single field establishes authenticity or value by itself.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-9d024231\"><strong>How to Use the Diamond Report Number<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-170f9cad\">The diamond report number is the starting point for verification.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-45430fde\">Enter it exactly as printed, including any leading zeros, letters or separators required by the laboratory. A typing error can produce a false \u201cnot found\u201d result.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fb0c8cd0\">The online record should display information corresponding with the report. Compare the carat weight, shape, colour, clarity, measurements and date instead of stopping when the number produces a result.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0fc65a3e\">A report number is not a serial number proving ownership. It identifies a laboratory record associated with an examined item.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-0c2d1467\"><strong>How to Verify a GIA Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2448f1fc\">Open GIA\u2019s official Report Check service and enter the report number.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0cbe7ff5\">Compare the online result with every major field on the document. The report type, issue date, shape, measurements, carat weight, colour, clarity and cut-related information should correspond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5c605ccf\">Some GIA services provide a downloadable digital report or additional images. Available features depend on the report type and date.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f6cc32fb\">If the record differs from the document, stop and investigate. Do not assume that a paper containing a valid GIA number is authentic simply because the number exists.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-0a95dbcc\"><strong>How to Verify an IGI Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0b8ec0c9\">Use IGI\u2019s official report-verification page and enter the unique report number. Some reports may also contain a QR code, but the official database should remain the reference point.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-416d4495\">Compare the returned record with the report\u2019s description, shape, measurements and 4Cs information.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8c4da057\">Confirm whether the report describes a natural diamond, laboratory-grown diamond or complete jewellery item. Those categories must not be treated as interchangeable.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5aa05661\">Where a laser inscription is stated, it can support physical matching under magnification.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-3356a53e\"><strong>How to Verify an HRD Antwerp Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a5786566\">Use HRD Antwerp\u2019s official report-check service and enter the report number shown on the document.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4e74f16a\">Review the returned report data and compare it with the physical document. Pay attention to the colour and clarity scales because HRD terminology can differ from that used on another laboratory\u2019s report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-801a2e80\">Confirm whether the report covers a natural diamond, laboratory-grown diamond, coloured diamond or jewellery item.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-139e8dee\">If the record cannot be located, check the number carefully and contact the laboratory or a qualified professional before concluding that the document is false.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-512f64f7\"><strong>Why Online Verification Is Not Enough<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-120f4418\">Online verification confirms that a laboratory has a record under that number. It does not prove that the stone being offered is the diamond described.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-21c622cb\">A genuine report can be copied. Its number can also be inscribed fraudulently onto another stone or placed on an imitation document.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-64080f28\">The buyer should match the physical diamond using several characteristics. Shape, measurements, weight, clarity features and inscription provide stronger evidence when considered together.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5298b90d\">For a valuable diamond, specialist origin and treatment testing may also be required. Visual inspection alone cannot always distinguish a natural diamond from a laboratory-grown diamond or detect sophisticated treatments.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-9953a1e5\"><strong>How to Read the Report Date<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7c9d2130\">The report date shows when the laboratory examined the diamond. It is not an expiry date.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a42564dd\">A diamond\u2019s inherent carat, colour and clarity characteristics are generally stable, but its physical condition can change. The stone may be chipped, abraded, repolished or recut after grading.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-24b9f960\">Treatments may also have been applied after the original examination. A setting can be changed, and the report may become separated from the item it originally described.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6361eba3\">An older report can still be useful when it is authentic and matches an unchanged stone. Physical inspection determines whether its description remains accurate.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-2a58ffff\"><strong>Natural vs Laboratory-Grown Description<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3fe8fcc5\">One of the most important report fields is the description of the diamond\u2019s growth origin.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-41f4f4ee\">The document should indicate whether the laboratory identified the stone as natural or laboratory-grown. Never infer origin from appearance, price or a seller\u2019s verbal statement.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d7d830d3\">A laboratory-grown diamond is a real diamond, but it participates in a different resale market from a natural diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ade04369\">\u201cNatural\u201d in this context does not necessarily identify the country or mine where the diamond originated. Geographic origin requires specific evidence and, in some cases, a dedicated origin-report service.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-203100b6\"><strong>How to Read Shape and Cutting Style<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f04e4267\">Shape describes the diamond\u2019s face-up outline, such as round, oval, cushion, emerald, pear, radiant or marquise.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-03e4164a\">Cutting style describes the arrangement of facets. A report might use descriptions such as round brilliant, oval brilliant or emerald cut.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fb0ef78c\">The physical diamond should clearly correspond with this field. A report for a round brilliant cannot belong to an oval stone even if the carat, colour and clarity appear similar.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1a27f643\">For unusual or antique cuts, the description may differ from everyday jewellery terminology. A professional can explain how the laboratory classified the stone.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-c53405ae\"><strong>How to Read Diamond Measurements<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-40b899b8\">Diamond measurements are recorded in millimetres.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8fb03c7f\">A round diamond is normally described using its minimum diameter, maximum diameter and depth. Fancy shapes are generally recorded through length, width and depth.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-028811e0\">Measurements help distinguish one stone from another and reveal how the carat weight is distributed. Two one-carat diamonds can have different face-up dimensions.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b5724721\">A mounted diamond can be measured approximately, but the setting may obstruct the girdle or pavilion. Small tolerances are possible, so professional interpretation is important.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2c3eb4de\">A substantial measurement mismatch is a warning sign that the report may not belong to the stone.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-6cd216ee\"><strong>How to Read Carat Weight<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e678241f\">Carat is a measure of weight. One metric carat equals 0.20 grams.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0e90599b\">Laboratories weigh loose diamonds using precise equipment. A report might record 0.99, 1.00, 1.01 or another exact weight.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8d810b07\">A mounted diamond cannot normally be weighed separately without professional removal. An appraiser may estimate its weight from measurements, but that estimate is not equivalent to a laboratory weighing.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d76608ae\">Do not remove a diamond merely to confirm carat weight before obtaining professional advice. The setting may have independent brand, antique or craftsmanship value.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-ca0456cf\"><strong>How to Read Diamond Colour Grade<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d66a9ae3\">For natural diamonds in the standard colour range, D represents colourless, with increasing traces of yellow, brown or grey towards Z.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6134e988\">Each letter represents a narrow range rather than an exact point. The report\u2019s laboratory and scale must be considered when interpreting the grade.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-66dd8f0b\">Fancy-colour diamonds use a separate system involving colour hue, intensity and distribution. A Z-colour diamond should not automatically be described as Fancy Yellow.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d62a5c6f\">The report comments should be checked for colour treatment. A treated diamond should not be compared directly with a naturally coloured diamond based only on appearance.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aca27e3a\">Read our guide to<a href=\"https:\/\/sothisdiamonds.com\/nl\/diamond-color-grade-resale-value\/\"> how colour grade affects diamond resale value<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-ffc34ac2\"><strong>How to Read Diamond Clarity Grade<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d4088369\">Clarity evaluates the relative absence of internal inclusions and surface blemishes.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3d9a7df7\">The GIA scale ranges from Flawless through Internally Flawless, VVS, VS and SI to Included grades. Other laboratories may use different abbreviations, so consult the scale on the report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c404d6fa\">Clarity is assessed under controlled conditions and magnification. An SI diamond may appear clean without magnification, while another stone with the same grade may contain a more visible inclusion.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6025cdd9\">The plot and report comments can explain why the grade was assigned. The physical inclusion appearance and current condition still require examination.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e0ccae5d\">Our detailed guide explains<a href=\"https:\/\/sothisdiamonds.com\/nl\/diamond-clarity-resale-value\/\"> how clarity and inclusions affect diamond resale value<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-8904f9ee\"><strong>How to Read the Clarity Plot<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5a757cb0\">A clarity plotting diagram maps important internal and external characteristics.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ed788ebe\">On many GIA plots, red symbols indicate internal characteristics, while green symbols represent external features. Always use the legend printed on the report because colours and symbols can vary by laboratory.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b6491766\">The plot can help identify the diamond because no two stones are expected to have the same pattern of characteristics in precisely the same positions.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c18c9d53\">A plot is not always a complete microscopic map. Some characteristics may be described in comments, and some compact report types may omit the plot entirely.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7028c45c\">Professional matching requires the plotted features to be located in the physical diamond under magnification.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-08b80942\"><strong>How to Read the Cut Grade<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8baf0d31\">Cut grade evaluates aspects of a diamond\u2019s proportions, light performance and workmanship where an applicable grading system exists.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4060d2c4\">On a standard GIA report, an overall cut grade applies to qualifying round brilliant diamonds in the D-to-Z range. Fancy shapes do not receive that same overall GIA cut grade.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-76f7947b\">Do not assume that an oval or emerald diamond is poorly cut because the field is absent. Its proportions, polish, symmetry, outline and appearance must be evaluated differently.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dcf6b917\">Similarly, the word \u201cExcellent\u201d should be interpreted within the issuing laboratory\u2019s system rather than treated as a universal guarantee.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7b7d855e\">Read more about<a href=\"https:\/\/sothisdiamonds.com\/nl\/diamond-cut-grade-resale-value\/\"> how cut grade affects diamond resale value<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-f2623cd3\"><strong>How to Read Polish and Symmetry<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2a0c5d20\">Polish describes the quality and condition of the facet surfaces. Symmetry describes the precision of the outline and facet arrangement.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a5e623a5\">These grades commonly range from Excellent to Poor, although terminology can vary.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-91b0d110\">A diamond with Excellent cut may have Very Good polish or symmetry. Triple Excellent means that the overall cut, polish and symmetry grades are all Excellent on an applicable round-brilliant report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9daaf5b8\">Current condition matters. Abrasion or later repolishing may mean an old report no longer fully describes the stone.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-23c384b6\"><strong>How to Read Fluorescence<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-afc6dab1\">Fluorescence describes the diamond\u2019s reaction to long-wave ultraviolet light.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-47aa1727\">Common intensity descriptions include None, Faint, Medium, Strong and Very Strong. Blue is the most frequently encountered fluorescence colour.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-067f8058\">Fluorescence does not change the laboratory colour grade. Its effect on appearance and market demand can be positive, negative or neutral depending on the diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dd6baf77\">Strong fluorescence does not automatically mean the stone is hazy. Transparency must be examined physically.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-543d5b87\">Our guide to<a href=\"https:\/\/sothisdiamonds.com\/nl\/diamond-fluorescence-polish-symmetry-value\/\"> fluorescence, polish and symmetry resale value<\/a> explains these characteristics further.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-204a2ce0\"><strong>How to Read the Proportions Diagram<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1ad6d580\">A proportions diagram shows information about the diamond\u2019s physical design.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ee7b449d\">Depending on shape and report type, it may include table percentage, total depth, crown angle, pavilion angle, girdle thickness and culet information.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a62e93e5\">These numbers help a buyer understand weight distribution and potential appearance. They should not be interpreted independently.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cf4542f6\">There is no single measurement that proves a diamond is beautifully cut. The angles, percentages, finish and physical appearance work together.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-aef6b77e\"><strong>Why the Girdle Description Matters<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-856e2cd8\">The girdle forms the outer edge between the crown and pavilion.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3bba4779\">A very thin area may be more vulnerable to damage, while a very thick girdle can retain weight without increasing face-up size. Girdle thickness can also vary around the stone.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7ac52c69\">The laser inscription, when present, is generally placed on the girdle. A setting may conceal it.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-975b782b\">The girdle description contributes to cut and durability assessment but does not determine value alone.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-4ba1fc49\"><strong>How to Read Culet Information<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f07591bc\">The culet is the small facet or point at the bottom of the pavilion.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c0932472\">Many modern diamonds have no culet or a very small one. Larger culets can be intentional in antique diamonds and may be visible face-up.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cdb69be8\">A large culet does not automatically indicate damage. In an old European or old mine diamond, it may be part of the historical cutting style.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2d50ca31\">The buyer should interpret it according to the diamond\u2019s age, shape and market.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-1a50bd16\"><strong>Why Report Comments Are Important<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-52d796ba\">Report comments can disclose information not fully represented in the headline grades or plotting diagram.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-509a950a\">They may refer to laser inscriptions, treatments, internal graining, clouds, clarity characteristics not shown, additional facets or other identifying observations.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aed82273\">A comment can materially affect resale interpretation. Never submit only a cropped image of the 4Cs.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5a605d69\">Upload every page and keep the comments legible. A buyer should explain any value adjustment based on a report comment.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-6f2ffd3d\"><strong>How Treatments Appear on a Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-eddd202a\">Appropriate laboratory reports may disclose detected colour or clarity treatments according to the laboratory\u2019s policies.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d467dd3f\">Examples include laser drilling, HPHT processing, irradiation or other treatment. Fracture-filled and coated diamonds may require different report services or identification documents.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-13469691\">Treatment information can appear in the description, results or comments. It should never be hidden when requesting an offer.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6839cc82\">A natural diamond with treated colour is not equivalent to an untreated natural diamond of similar visible colour.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-b8065601\"><strong>How to Check a Laser Inscription<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f1c4651b\">A laser inscription is microscopic wording or a number placed on the diamond\u2019s girdle.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0bbd55f8\">It is not normally visible without magnification. A professional can rotate the diamond under a loupe or microscope to locate and read it.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-957ac072\">Compare the inscription exactly with the report and official online record. The measurements and other identifying characteristics should also match.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-eebf787e\">A missing inscription does not automatically invalidate a report because not every report service includes one. A setting can also hide part of the girdle.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-b7247464\"><strong>Why an Inscription Alone Cannot Prove Identity<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f5982865\">A report number can be copied or fraudulently inscribed.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-45e7c011\">The inscription must therefore be supported by the correct shape, measurements, quality characteristics and, where available, clarity plot.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1b658981\">Professional verification may also include testing the material and confirming whether it is natural or laboratory-grown.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7f5d23b5\">Treat the inscription as one useful identifier\u2014not as complete proof.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-97cb2a29\"><strong>Paper Reports vs Digital Reports<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-353b9190\">Some laboratories issue paper reports, while others provide digital-only documents for certain services.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f8c2fb38\">A digital report is not automatically less legitimate. Its authenticity depends on whether it is available through the issuing laboratory\u2019s official system and matches the diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-498e388c\">A paper report is not automatically genuine. Printing quality, logos and security features can be imitated.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-535acfc4\">The official database and physical diamond match are more important than whether the document is printed.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-1876836d\"><strong>Security Features on a Paper Report<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-504e7b39\">Laboratory reports may include holograms, microprinting, security screens, specialised paper or other anti-counterfeit features.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-059dd5bc\">These features vary by laboratory, report type and issue date. Do not reject an older document because it lacks a feature used on newer reports.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-31d36861\">Security features can support authenticity, but they should not replace online verification.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-37045aeb\">If the document appears altered, has inconsistent fonts or contains information that differs from the online record, request professional review.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-b2881007\"><strong>What If the Report Number Cannot Be Found?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9e081fd4\">First, re-enter the number carefully. Check for leading zeros, letters, spaces or confusion between similar characters.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-44c23e19\">Confirm that you are using the correct laboratory\u2019s official verification service. A number from an appraisal or retailer is not necessarily a laboratory report number.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-436bad09\">Older reports or unusual services may require direct contact with the issuing laboratory.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-388fb471\">Until the document is verified, treat its grades as unconfirmed. Do not advertise the diamond using unsupported laboratory claims.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-7082af9e\"><strong>What If the Online Record Differs From the Paper?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-88abaf42\">Stop the transaction until the discrepancy is explained.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cd1d3ea9\">A minor formatting difference may result from an updated digital presentation, but the identifying and grading data should correspond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-31b545c0\">Differences in carat, shape, measurements, colour or clarity are significant. The paper could be altered, paired with the wrong report number or associated with another diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-51c283b4\">Contact the laboratory or obtain independent professional inspection before proceeding.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-265a3a4f\"><strong>How to Match Measurements With a Mounted Diamond<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ffaa88ef\">A professional can often estimate or partially measure a mounted diamond, but metal may obstruct some dimensions.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9214ebc9\">The reported shape and visible measurements should still be broadly consistent. A large mismatch is not explained simply by the setting.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0257cb91\">Exact weight cannot normally be confirmed while the diamond remains mounted. If removal becomes necessary, it should be performed professionally after evaluating the setting.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a62a59bf\">Do not damage a branded or antique ring merely to conduct a check that may be completed through other identifying characteristics.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-dd960d8d\"><strong>How to Match a Clarity Plot With the Diamond<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d2fdbcd4\">A gemologist uses magnification to locate the inclusions and blemishes represented on the report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5c34b412\">The position, type and relationship of these characteristics can create an identifying pattern. A central crystal, feather near the girdle or group of pinpoints may support the match.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-edb325cd\">The process requires skill because facet reflections can make one inclusion appear multiple times.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aa94f5c4\">A plot mismatch can indicate the wrong diamond, later recutting or an incomplete interpretation. It should be investigated rather than ignored.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-0de01750\"><strong>Does the Report Still Apply After Recutting?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-97498af0\">Usually not in its original form.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ef12c245\">Recutting can change carat weight, measurements, shape, cut, polish, symmetry and clarity. The laser inscription may also be removed.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5c49eb25\">Even limited repolishing can alter dimensions or surface characteristics.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-def526be\">A diamond that has undergone material alteration may require an updated report before the old grades are used in a sale.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-535c0ca5\"><strong>Does the Report Still Apply After Damage?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1de696e1\">It can remain useful for identification, but it may not describe current quality accurately.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-673bf832\">A new chip can affect clarity, weight and durability. Abrasion may change polish or condition.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-32120b12\">The buyer should distinguish between an authentic historical report and the stone\u2019s present state.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dd99c905\">Any offer adjustment should be based on the actual damage and likely repair consequences.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-a44c437e\"><strong>Grading Report vs Insurance Appraisal<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-af1e74e3\">A grading report describes gemological characteristics. An insurance appraisal generally estimates replacement value.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fd71dc95\">The appraisal figure may be substantially different from the amount available through resale. It can also include the setting, taxes, retail margins and replacement considerations.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bee22c74\">A grading laboratory does not normally state what a buyer must pay.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f6597717\">When selling, the relevant figure is the current market offer for the verified diamond or jewellery\u2014not the insurance replacement amount.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-ac6062ed\"><strong>Grading Report vs Purchase Receipt<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e92caae2\">A receipt shows what someone paid at a particular time and may help establish provenance.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f9f93e8e\">It does not prove current value, condition or grading accuracy. The retail price may include taxes, design, brand, store costs and services.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-63fb2662\">The grading report provides more useful quality information, but it also does not establish resale value alone.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-66f2a227\">Submit both documents when available, but understand their different purposes.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-8a62abde\"><strong>Does a Grading Report Prove Ownership?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-77e3a731\">No. A report follows the diamond\u2019s identifying characteristics, not the identity of its legal owner.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-40e5b875\">A seller may still need identification, proof of ownership, inheritance information or other transaction documents.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-df926890\">A report number should never be treated as authority to sell an item.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1a177c73\">Read our guide to<a href=\"https:\/\/sothisdiamonds.com\/nl\/documents-needed-to-sell-a-diamond\/\"> documents needed to sell a diamond<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-d97fa6b1\"><strong>Does a Verified Report State the Diamond\u2019s Resale Value?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4f12d73f\">No. Verification confirms the report record and helps identify the diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6f44dcc2\">The buyer must still calculate value using the verified grades, physical condition, origin and current demand.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5c361f11\">Two diamonds with the same grades can receive different offers because of inclusion appearance, proportions, shape, fluorescence or condition.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1ad6bb5c\">Our pillar guide explains<a href=\"https:\/\/sothisdiamonds.com\/nl\/how-diamond-buyers-calculate-an-offer\/\"> how diamond buyers calculate an offer<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-1b087a95\"><strong>Illustrative Example: Valid Number, Wrong Measurements<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-be835afb\">Imagine a fictional report for a 1.01-carat round diamond measuring approximately 6.4 millimetres across.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1b870602\">The online record is genuine, but the diamond presented with it measures significantly less and has different proportions.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b7fa090c\">The valid report number does not resolve the mismatch. The buyer should stop and determine whether the wrong stone or document has been supplied.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-09ca04b9\"><strong>Illustrative Example: Correct Report, Later Chip<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0c773d09\">Consider a fictional oval diamond with a genuine, verifiable report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-eb0fb2e1\">The measurements and inscription match, but physical inspection reveals a chip near one end that is not documented on the older report.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fc46cd4f\">The report still helps identify the diamond, but the final offer must account for current condition, possible repair and weight-loss risk.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-4ec67f98\"><strong>Illustrative Example: A Hidden Inscription<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1bbc3fdf\">Imagine a diamond ring whose verified report states that the girdle carries a laser inscription.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1c3bcc0f\">The inscription cannot be seen because a prong covers that part of the girdle. This does not automatically prove a mismatch.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a3d9d619\">A professional may use measurements and clarity characteristics first. Removal should only be considered if required for the final verification.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-d28bfe45\"><strong>Illustrative Example: Natural vs Laboratory-Grown Confusion<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-30a3ca62\">Suppose a seller uploads a report and describes the diamond as natural.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9ef0e105\">The document\u2019s description actually states that the stone is laboratory-grown. The carat, colour and clarity fields cannot be used to value it as a natural diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b664ac03\">The origin field must be read before any price comparison is made.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-31d6440a\"><strong>Illustrative Example: A Missing Clarity Plot<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e5091f15\">A compact report contains colour, clarity, carat and measurements but no plotting diagram.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-035586c2\">The absence of a plot does not automatically make the report invalid. The selected service may not include one.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2434fd9e\">The buyer can use the report number, inscription, measurements and physical examination to establish whether the diamond matches.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-e5b18cdf\"><strong>Preparing a Report for an Online Valuation<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cd1dc5ec\">Scan or photograph the complete report in clear, neutral light. Include every page, comment, scale, barcode and report number.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7fdb892c\">Do not obscure the characteristics required for verification. You can remove unrelated personal information from invoices or appraisals before uploading them.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-31125eb0\">Photograph the diamond or complete jewellery item from the front, side and underside. Include the inside of the band if it contains hallmarks, serial numbers or signatures.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d2420d8c\">An online review can establish useful preliminary information. A final offer may still require physical verification.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-ab204f13\"><strong>Veelgestelde vragen<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-059d34a2\"><strong>How do I check whether a diamond certificate is real?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1dbdb235\">Verify the report number through the issuing laboratory\u2019s official website and compare the record with both the document and physical diamond.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-887ab210\"><strong>Where is the diamond report number?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9f267448\">It is normally printed prominently near the top of the report.

HRD Antwerp provides an official report-check service for supported reports.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-3bd90199\"><strong>Does a valid report number prove my diamond is genuine?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ff1dbdf9\">No. It proves the record exists. The physical diamond must still match it.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-631113c4\"><strong>Can a fake diamond have a genuine report number?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8567d340\">A valid number could be copied or fraudulently inscribed onto another material or stone. Professional matching is essential.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-17dd332b\"><strong>Can someone copy a diamond certificate?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aec165cf\">A document or number can be copied. That is why database and physical verification are both required.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-908430d6\"><strong>Should I trust a report QR code?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e890f7d1\">Use it cautiously and confirm that it leads to the laboratory\u2019s official domain. You can also type the official address manually.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-198b3506\"><strong>Is a screenshot of a report enough?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-324f1f77\">No. Verify the number independently and request the complete document.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-3e49af3a\"><strong>Is a digital diamond report genuine?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1e4a58e0\">It can be. Some laboratory services are digital-only. Verify it through the official database.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-313a82ff\"><strong>Is a paper certificate automatically genuine?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5fa8f279\">No. Paper documents can be altered or counterfeited.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2dfd38e1\"><strong>What information should match the online report?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a713d981\">The report type, date, shape, measurements, carat, colour, clarity and other grading fields should correspond.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-eabe653f\"><strong>What if one field does not match?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ca77a623\">Stop and investigate. A material discrepancy may indicate an altered document or mismatched diamond.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-98e57686\"><strong>Can two diamonds have the same carat, colour and clarity?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-63308b55\">Yes.

Measurements, weight, shape and clarity characteristics can also support matching.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2063beb9\"><strong>What does the report date mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-629b0ead\">It is the date the laboratory examined the diamond. It is not necessarily an expiry date.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-1878dc0f\"><strong>Do diamond grading reports expire?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c291248d\">They do not usually have a simple expiry date, but condition or report relevance can change.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-e2fc47c7\"><strong>Is a twenty-year-old GIA report still useful?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-baa37a2d\">Potentially. It should be verified and the diamond\u2019s current condition should be inspected.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-e8ab1356\"><strong>Should I update an old report before selling?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f1cb41e1\">Not automatically. Obtain an initial assessment and compare the expected benefit with the fee, time and risk.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2937bf30\"><strong>What does \u201cnatural diamond\u201d mean on the report?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c70ff016\">It means the laboratory identified the examined stone as naturally formed rather than laboratory-grown.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-887e3df0\"><strong>Does natural origin identify the mine?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d2fa6a5f\">No. Geographic origin requires separate evidence or a specialised origin-report service.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-8e73640a\"><strong>How can I tell whether the report is for a lab-grown diamond?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-eb14d21d\">Read the description and report title. Do not infer origin from the 4Cs alone.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-049b225f\"><strong>Can natural and lab-grown reports look different?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-88971184\">Yes. Laboratories may use distinct formats or terminology to differentiate them.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-e56b0781\"><strong>What does carat mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5964764d\">Carat measures weight. One carat equals 0.20 grams.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-9d55fc4e\"><strong>Can I confirm exact carat weight while the diamond is mounted?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-42c24d74\">Normally not without professional removal. Measurements can only support an estimate.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-babfc876\"><strong>What do the three diamond measurements mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1ddec998\">For a fancy shape, they generally represent length, width and depth. A round normally uses minimum diameter, maximum diameter and depth.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-12956c9f\"><strong>Why do two one-carat diamonds have different measurements?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-186e6dd8\">Carat measures weight, and that weight can be distributed differently through the diamond.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-dc57e2a1\"><strong>What does D colour mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-538693c9\">D is the highest colourless grade on the standard D-to-Z scale.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-b968df45\"><strong>Is Z a fancy-yellow diamond?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b472b980\">No. Z remains within the D-to-Z range. Fancy colour uses a separate grading system.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-dffd591d\"><strong>What does VS2 clarity mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5eb4ac25\">It indicates minor inclusions within the relevant grading system. Actual inclusion type and position still matter.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-7df927ee\"><strong>What is a clarity plot?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f11989ba\">It is a diagram mapping important inclusions and blemishes.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2551cadb\"><strong>Does every report include a clarity plot?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-48bf6017\">No. Some compact or digital report types may omit it.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2b8590ab\"><strong>Does the clarity plot show every inclusion?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bfe6b948\">Not necessarily. Some characteristics may be described in comments or omitted from the simplified plot.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-de67ed07\"><strong>What do red and green marks mean on a GIA plot?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0d446bd8\">Red commonly represents internal characteristics and green represents external features. Always check the printed legend.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-9f06e191\"><strong>Can a clarity plot identify a diamond?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-07647cab\">It can support identification when its characteristics are matched under magnification.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-aeca15f1\"><strong>What does Excellent cut mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d15a59ab\">It is the highest grade within an applicable cut-grading system. It does not guarantee a particular resale value.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-902da215\"><strong>Why does my oval report have no cut grade?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-23770954\">Standard GIA reports do not assign the same overall cut grade to fancy shapes such as oval.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-32774191\"><strong>What are polish and symmetry?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2b1b3b03\">Polish assesses facet-surface quality, while symmetry assesses outline and facet alignment.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-d154fa18\"><strong>What is Triple Excellent?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d62a0271\">It describes a qualifying round brilliant with Excellent cut, polish and symmetry.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-4050e01a\"><strong>What does None fluorescence mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ecdb03df\">It means the reaction falls within the laboratory\u2019s None category under its standard testing conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-9ba59bd6\"><strong>Is Strong fluorescence bad?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-56e33689\">Not automatically. Transparency, body colour and actual appearance must be evaluated.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-efae2730\"><strong>What is the proportions diagram?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-838e091a\">It records measurements and relationships such as table, depth, crown, pavilion, girdle and culet where applicable.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-e124f7c0\"><strong>What does a thick girdle mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-770ea454\">It indicates greater thickness around the diamond\u2019s outer edge. Its effect depends on the complete proportions.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-5b8cb532\"><strong>What does \u201cculet: none\u201d mean?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-433f10ea\">It means there is no additional flat facet of reportable size at the pavilion\u2019s bottom.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-e4002e89\"><strong>Why are report comments important?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b3dd1d6a\">They can disclose treatments, inscriptions, graining or characteristics not fully shown elsewhere.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-9c688b60\"><strong>Where are treatments listed?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cacf13c9\">They may appear in the description, grading results or comments, depending on the laboratory and report.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-b4259aa6\"><strong>Can a treated diamond still have a report?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2ea3181d\">Some treated diamonds can receive an appropriate report, while others may receive an identification document rather than a standard grading report.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-3015358a\"><strong>Does a certificate show the diamond\u2019s price?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-543f3471\">A grading report normally does not state current resale value.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-8b6548f4\"><strong>Is the price on my appraisal the resale value?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0dca1bc6\">Usually not. Insurance appraisals generally estimate replacement cost.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-7df308d0\"><strong>Does a purchase receipt prove current value?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4a310f20\">No. It shows a historical transaction, not present market value.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-bfa1c0b6\"><strong>Does a grading report prove I own the diamond?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7849bd8d\">No. Ownership and authority to sell require separate evidence.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-8bbff159\"><strong>What if the paper report is lost?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1f46994e\">The online record may still be available. A buyer can also assess a diamond without the original report.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-7df426a5\"><strong>Can I sell a diamond without a certificate?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aa355449\">Yes. Additional physical testing and grading may be needed before a final offer is confirmed.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-1dcee668\"><strong>Should I pay for a replacement report?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aa3ebac0\">Only when the expected improvement in the sale outcome justifies the expense and risk.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-d43eb8b3\"><strong>Can a buyer reduce the offer if the report does not match?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c94c6ff1\">Yes. A mismatch creates uncertainty and may require additional testing. The buyer should explain the issue.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2129243c\"><strong>Can damage make the report inaccurate?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d5ef5755\">Yes. A later chip, abrasion or recut can change the diamond\u2019s documented condition or grades.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-d49822a9\"><strong>Should I remove the diamond to check the report?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b2e59b46\">Not yourself. Professional removal should only be considered when necessary.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-51eb0ec7\"><strong>Can a mounted diamond still be verified?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e2aba5ed\">Often, yes. The report number, visible measurements, inscription and clarity features may provide sufficient initial evidence.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-48f10524\"><strong>How should I upload my report for a valuation?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1896f523\">Upload every page clearly and include the report number, comments, measurements and scales.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-3c1692e6\"><strong>Should I crop the report number from my submission?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4acabb87\">No. A professional buyer needs it for verification. Remove only unrelated personal information from other documents.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-8b779e42\"><strong>Can Sothis verify my diamond report?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9cfc0f9c\">Sothis can review your report, check available laboratory records and compare the documented information with the diamond during physical verification.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-d6556006\"><strong>Verify Your Report and Request a Market-Based Offer<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3cda275c\">A grading report is useful only when it is authentic, complete and correctly matched to the physical diamond.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-418f5700\">Begin by submitting the full report and clear photographs of the diamond or jewellery. Sothis Diamonds can review the report number, origin, grades, measurements, comments and available identifying information.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d38e6e47\">If the original document is missing or cannot be verified, you can still request an assessment using the information available.
