At GGS, we understand that it is all too easy to make the mistake of purchasing a diamond of lower value than you were led to understand. This is why obtaining the Diamond Certificate is critical for your informed diamond purchase.

A Diamond Certificate is a document issued by a Gemological Laboratory that proves the diamond has been evaluated by experienced diamond graders, and judged to be of a certain value based on its unique characteristics as reviewed by various gemological instruments and processes. Diamond certificates may only be issued for loose diamonds not already mounted in a jewelry setting. Even the most microscopic inclusions may have a major effect on the value and overall quality of the diamond, making a detailed evaluation essential for diamond shoppers and sellers alike.

While GSS strives to provide detailed information to equip consumers with the facts that will enable them to make informed decisions when diamond shopping, the truth is that only highly skilled and professionally trained experts in gemology can truly evaluate a diamond down to the most detailed characteristics. When grading a diamond, gemologists use highly advanced spectrometers, as well as multiple types of sophisticated equipment. Your diamond’s certification will contain the defining characteristics and grading of your stones clarity, cut, karat weight, and color. This certificate does not establish the monetary value of your diamond, but rather offers a straightforward evaluation of the critical factors about the stone that do effect the value, quality, and appearance. A certificate is also necessary to use for identification purposes should your diamond become lost or stolen; having a professional certificate in place will greatly facilitate replacing the diamond with another of equal value. Your professional certificate should always include the following:

• Date of issue of the report
• A unique ID number for file lookup and tracking
• Name of the company and gemologist issuing the report
• Origin of the diamond, whether treated or naturally occurring
• Exact measurement of karat weight
• Detailed description of shape and cut
• Precise measurements and proportions
• Clarity and color grades
• Fluorescence
