The diamond certificate is a statement issued by an independent gemological laboratory that the diamond being evaluated has been examined by an experienced diamond grader. Star Facets strongly recommend you buying a diamond that is accompanied with a diamond certificate. We only sell diamonds that are accompanied with a certificate. GIA and AGS independent gemological laboratories are more accurate and reputable labs that we recommend and sell. There are other independent laboratories out there that are accompanied with a diamond but we recommend GIA and AGS laboratories. If you are interested in a diamond that is not accompanied with a diamond certificate, have a jeweler send it out to a reputable independent gemological laboratory to have it examined by an experienced diamond grader so that the diamond would have its own unique characteristic. With this being done, you would be able to always identify your diamond. Some of the characteristics that are shown on the diamond certificate are as listed: shape, measurements, weight, color, clarity, proportions, finish, and fluorescence as seen in the diamond while being evaluated using various high-tech gemological instruments. Listed below is information to help you understand and be more familiar with GIA and AGS diamond laboratories that we offer and respect. Please take the time and visit the diamond laboratory websites by clicking on their images below for further information.
