The diamond certificate records all the relevant information pertaining to the diamond including carat weight, colour grade, clarity grade, measurements and physical properties.

All diamonds sold by International Diamond Group Come with certificates. These certificates also serve as proof of the diamond's identity and value.

Most of these certificates are already displayed on the site when clicking in "View Certificate" link.
