A diamond certificate offers valuable information and takes into account the 4C’s when the diamond was priced. Each diamond is unique and a certificate will identify the special characteristics of your diamond.
When you purchase a diamond that comes certified from one of the three certiying labs (GIA, AGS, IGI and EGL) you are assured of the diamonds value. These labs do not sell diamonds, they only grade them and therefore do not benefit from grading diamonds favorably.
