What is Gemprint®?
Gemprint® is an identification system for diamonds that records the unique and subtle distinctions in diamonds, just as fingerprinting does for people. Completely noninvasive, Gemprint® technology works by shining a low-powered red laser light at a diamond, which is refracted within the diamond and reflected from every facet and internal characteristic. The light coming back from the diamond is a distinct 'optical fingerprint' that is recorded and saved in a database that can be shared instantly among a global network of jewelers, law-enforcement and government officials. Gemprints can be matched and retrieved in seconds. As forensic evidence, Gemprint® has been used by the FBI and the Canadian Government since its invention in 1976. Gemprint® has the ability to detect simulants and discern the optical light performance of loose or mounted diamonds and some transparent gemstones.
