Every diamond has its own visual signature. It's like a fingerprint - no two are alike

GemprintTM uses a non-invasive, low-powered laser to capture the unique sparkle pattern of each diamond and registers this image in its database.

Every diamond certified by Gem Certification & Assurance Lab (GCAL) is first Gemprinted and the sparkle pattern is reproduced on every diamond grading certificate along with the diamond grading information. GemprintTM gives customers peace of mind and confidence because they know their stone is registered and protected from swapping. And, because ownership information is stored in Gemprint's international database, the recovery of lost or stolen gems is made possible. It's really that simple.
