The 4 C's of Diamonds :
Diamond Certificates
A certificate is a "blueprint" of a diamond, it tells you the diamond's exact measurements and weight, as well as the details of its cut and quality. It precisely points out all the individual characteristics of the stone. Certificates also serve as proof of the diamond's identity and value. A certificate is not the same thing as an appraisal. A certificate describes the quality of a diamond, but it does not place a monetary value on the gem. An appraisal places a monetary value on your diamond, but does not certify the quality of the diamond. GIA Sample Certificate Who Issues Certificates? There are many diamond labs that issue certificates, and the Gemological Institute of America (GIA) and the American Gem Society (AGS) are two of many widely regarded and recognised diamond grading labs in the world. Not all diamond certificates are created equal but always ask for credentials of the certifying lab. And while there are many other diamond grading labs in operation (many of which produce their own grading reports), different labs have different grading standards, and some labs will be more lenient with their standards than others.
