What are diamond certificates (or Diamond Grading Reports)
A diamond certificate is also known as a Diamond Grading Report. This report comes from the Gemological Institute of America (GIA), and you should require this report when you are purchasing a diamond. With a diamond certificate, you can verify the color, cut, carat, weight, and clarity of the diamond. You donít have to worry about a diamond dealer telling you anything less than the truth, because the certificate comes from the GIA Ė not the dealer.
