The process, makes the identification of diamonds-especially of 1 carat and above, absolutely certain and invaluable if the diamond is lost or stolen. The process, called Gemprint, was developed by the Weizmann Institute of Science in Israel and is becoming widely used in the United States.
The current technology has been in use by Gemprint for nine years. During the 12 months ended on October 31, 2005, Gemprint has added digital "fingerprint" images for over 30,000 diamonds to its database of unique digital images of the refractive light patterns of individual diamonds. The aggregate number of diamonds registered in the Gemprint database is now in excess of 500,000.
A new certification service, that uses a patent-pending process for assurance that a diamond is in compliance with the Kimberley Process and the 2003 Clean Diamond Act. For the first time consumers will be able to purchase diamonds certified by an independent third-party that shows the source of the rough diamond and the original point of distribution. The unprecedented program, named the Source Veritas Passport, combines guaranteed grading of quality by a respected gem lab, along with unbiased assurance of the origin of the diamond.
