Paper Abstract

The commercial availability of gem-quality synthetic diamonds, and the expanding research on various methods of diamond synthesis, have made it necessary for the gem diamond trade to find simple ways to identify synthetic diamonds. Using both magnification and various types of spectroscopy and luminescence techniques, a number of properties that are characteristic of synthetic diamonds have been found.
