Whether or not these enhancement processes are considered acceptable trade practices, their use must legally be disclosed at the time of gemstone sales. Disclosure of treatment information requires that treated gems be correctly identified by gemologists and gemtesting laboratories. Treatment detection is based upon careful documentation of the properties of gem materials, including the use of advanced nondestructive techniques for obtaining chemical and spectral data.
