CERTIFICATE
Larger Diamonds, 1/2 carat and up, should be certified by the Gemological Institute of America (GIA) or American Gem Society (AGS). With some extremely fine diamonds, certifications start at 1/4 carat. The GIA and AGS certificates are IMPORTANT because they give you diamond - graded accuracy. There are certificates provided by other companies in the United States and other countries. The accuracy of these other companies is not equivalent.

Please be careful when selecting your diamonds and always view them under a microscope. Shop with confidence at The Classic Rock, as we only sell GIA- or AGS-certified diamonds.
