WGI CERTIFICATION
WGI Gemmological Reports intend to describe the characteristics of the article submitted for analysis to the laboratory but also give a valuable and useful tool to the jewellery Industry. The Reports, with their unique online report verification number, may contain results of loose or mounted diamonds or gemstones, features and characteristics of eventual precious metals present in the article analysed.
DIAMOND GRADING REPORT
The WGI Diamond Grading Report includes a detailed analysis of the diamond’s 4Cs – carat weight, color, clarity, and cut – which are the universally recognized criteria for evaluating a diamond’s quality. The report also includes information about the diamond’s shape, measurements, inclusions, polish, and symmetry. All of this information is used to assign a grade to the diamond, which is then included in the report.

LASER INSCRIPTION
A laser inscription in a diamond refers to a microscopic marking or inscription that is made on the girdle (the outer edge) or the table (the flat top surface) of a diamond using a laser. This inscription is typically a series of letters, numbers, symbols, or even a customized message, and it is done to provide additional identification, branding, or personalization to the diamond. The laser inscription is performed by skilled professionals using precise laser technology. It creates a permanent marking on the diamond’s surface without causing any damage to its structural integrity or visual appearance. The inscription is usually invisible to the naked eye and requires magnification to be seen clearly. The purpose of a laser inscription in a diamond can vary. It may serve as a means of identification, allowing the diamond to be easily traced and verified in case of loss, theft, or insurance claims. It can also be used to indicate important details about the diamond, such as its certification number, the logo or name of the diamond manufacturer, or a personal message for sentimental reasons. Laser inscriptions provide an additional layer of security and assurance for buyers, as they can verify the authenticity and characteristics of the diamond by matching the inscription with corresponding records or certificates. Additionally, some diamonds may have laser inscriptions that are linked to digital databases, enabling easy access to detailed information about the diamond’s grading, origin, and history.
