Diamond certificates

Identification and authentication

A diamond certificate is like a personal identity card that accompanies the gemstone. It comes in the form of a grading report attesting of the diamond's quality and authenticity, and documenting its specific characteristics. The certificate includes security features such as a hologram, a background screen, and microprint lines.

Laser inscription is a complementary service in which the unique report number is microscopically inscribed on the diamond's girdle. Optionally the gemstone can be sealed in a compact and tamper-resistant package incorporating key grading information (note: GIA suspended its sealing activities from November 2014 to February 2016).

The authenticity of the gemological report can further be verified online:
