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.
All Blue Nile Signature diamonds have been screened for Gemprint and must be registered at Gemprint®. Many insurance companies offer a 10% discount if your diamond is registered in the Gemprint® International Registry at Gemprint.com. For a list of companies, see Insurance Discounts.
