European Gemological Laboratory researchers Gregory Sherman and Branko Deljanin of EGL USA presented lectures in London at the Gemmological Association of Great Britain, and in Scotland at the University of Edinburgh and the British Geological Survey. The gemologists discussed their latest findings on high-pressure, high-temperature annealing of diamonds, including various processes used throughout the world as well as advanced techniques for identifying GE POL diamonds and colored enhanced diamonds. Attendees were presented with a copy of the new EGL publication “Changing the Color of Diamonds: The HPHT Process Explained.” The booklet is available to the industry by calling (212) 730-7380, extension 214.
