What is Gemprint?

GEMPRINT® is the world’s most sophisticated, non-invasive, positive identification technology that records the unique optical ‘fingerprint’ of each diamond. Just like a human fingerprint, every diamond has a unique GEMPRINT®.  Invented in 1976, this patented and proven technology has been used by the FBI and Canadian Government.

GEMPRINT® is currently used by:

  • Retail jewelers and their clients as a means of ensuring the identity of purchased diamonds

  • Gemological laboratories as an identification service offered as an adjunct to their grading and valuation services

  • Internet sites offering sale and auction of diamonds and diamond jewelry

  • Designers and manufacturers establishing branding programs for their unique diamond products

  • Manufacturers and cutters worldwide for inventory identification and comparison


When stolen jewelry is recovered, the diamond's GEMPRINT® can be matched with an ID in the database. The added security of Gemprint® entitles you to receive discounts from insurers in the U.S. and abroad.
