ABSTRACT:
The gemstone recordal and retrieval system records optical images for gemstones in an effective manner. The optical image of a gemstone is captured using a two-dimensional charge coupled device whereby the time to capture the image is relatively short. The optical images can be improved in definition by varying the output of a laser LED. This fast feedback and adjustability provides accurate recordings.
