ABSTRACT:
A system for the effective recording and recovery of gemstones uses site machines for recording the optical response of gemstones with these optical responses being forwarded to a central database for classifying in a manner to allow effective searching of the database. The site machine progressively scans the optical response of the gemstone and provides an accurate record of the optical response of the gemstone. Gemstones reported to the central database as being stolen have their records duplicated in a separate database which can be searched remotely by police and other enforcement agencies for a possible match with the optical response of gemstones they have recovered.
