What we do ?

The purpose of a diamond certificate is to offer you the highest possible level of security and confidence. It confirms the diamond’s authenticity and describes its essential characteristics. Grading diamonds is not an easy task. It needs to be examined by expert gemologists, under strict lighting and using specific gemological equipment. Diamond Certificates are invaluable documents that show in detail a diamond's credentials. They provide a unique fingerprint of a diamond which is a source of vital information to the trained gemologist, jeweller or consumer. A CDL certificate enables you to buy your diamond with confidence.
