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 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.
