Chart of Commercially Available Gem Treatments
Christopher P. Smith and Shane F. McClure
This chart combines a comprehensive listing of the commercially available treatments for the most commonly used gem materials with an indication of the current status of their detectability. Designed as a supplement to “Gemstone Enhancement and Detection in the 1990s,” from the Winter 2000 issue of Gems & Gemology, this chart makes the key information available in an easy-to-use reference tool.
