These diamonds often vary so slightly that they appear identical to the inexperienced eye. <\/span><\/p>\n\n\n\n<p>Similar-looking<span data-preserver-spaces=\"true\"> diamonds are easily mixed up and require a system for checking them back into their parcels. For example, imagine the confusion of showing a client three near-identical diamonds\u2014all identical in size and clarity, with<\/span> just one colour difference.<\/p>\n\n\n\n<p>As a result, small diamonds matched to their certificate numbers correctly identify each diamond by its inscription. Retailers must check diamonds back into parcels.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.serendipitydiamonds.com\/uk\/product\/r1h021-calais-4-claw-oval-engagement-ring-open-shoulders\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"639\" src=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2023\/02\/GIA-0.80-oval-engagment-ring.jpg\" alt=\"GIA certified diamond, oval cut, set into 18ct-yellow gold in the Calais design.

Tiny numbers pose a problem for many people who don&#8217;t have the knack or trained eye while using a 10x loupe. <\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">Manufacturers, retailers and consumers need to be able to view their inscriptions, but the size makes this an arduous task. The inscription size needs to be microscopic to fit discreetly on the girdle and to ensure the diamond&#8217;s beauty is unaffected.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-the-best-magnification-to-view-a-diamond-inscription\"><span data-preserver-spaces=\"true\">What is the best magnification to view a diamond inscription?<\/span><\/h2>\n\n\n\n<p><span data-preserver-spaces=\"true\">Based on the magnification of the viewer we sell (see below), the magnification is 20x. It will always take a little time to<\/span> set up<span data-preserver-spaces=\"true\"> to view the inscription, but provided the number is not too faint, it should be visible at this magnification. For most people, a standard diamond loupe (10x) will struggle to provide enough magnification to read the full number.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-useful-tools-for-viewing-the-gia-laser-inscription\"><span data-preserver-spaces=\"true\">Useful tools for viewing the GIA laser inscription<\/span><\/h2>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-9781\" style=\"font-size: 16px;\" title=\"GIA laser inscription viewer\" src=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2015\/09\/GIA-Laser-Inscription-Viewer.jpg\" alt=\"GIA laser inscription viewer\" width=\"850\" height=\"583\" srcset=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2015\/09\/GIA-Laser-Inscription-Viewer.jpg 750w, https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2015\/09\/GIA-Laser-Inscription-Viewer-300x206.jpg 300w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">If you want to make viewing more manageable, we recommend the Laser inscription viewer. This handy well-constructed device works with a diamond held within a ring mount or ring clip. An adjustable magnifying glass rests at the end of an arm, which glides effortlessly around the diamond&#8217;s outer edge, allowing the user to scan for the GIA inscription. <\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">Once found, adjust the lens for a clear view of the GIA number. It will take the user a little time to become acquainted with the viewer, but using this instrument will make the inscription easier to read.<\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">As a bonus, the viewer includes a hearts-and-arrows viewer for loose diamonds concealed within the scope&#8217;s body. (Shown here alongside the inscription viewer.)<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-advice-for-purchasing-with-a-gia-laser-inscription\"><span data-preserver-spaces=\"true\">Advice for purchasing with a GIA laser inscription<\/span><\/h2>\n\n\n\n<p><span data-preserver-spaces=\"true\">If you buy a GIA-certified, laser-inscribed diamond, consider the following information.<\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">1. In-store &#8211; ensure that your retailer has a viewer so that you can see this critical feature of the diamond. Many buyers do not require this level of detail, but some clients enjoy the reassurance of seeing their inscription.<\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">2. If you decide upon a GIA-certified diamond engagement ring with a laser inscription, speak to your jeweller about positioning the diamond so that the number remains visible when the diamond goes into the ring.<\/span> Most diamond rings feature claws or settings that obscure the inscription on the edge of the diamond. <\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">Finally, if you are looking for a specific GIA-certified<\/span> diamond, we offer an extensive catalogue on our website as part of our loose diamond service. Some even feature traceability back to the mine of origin.
