NEWS & REPORTS FROM OUR GEM TREATMENT LAB - THINKING ALOUD by Ted Themelis

------------------- TRADE ALERT --- TRADE ALERT---- TRADE ALERT-----

Finally, the heat-treatment of synthetic ruby & sapphire is here...! Flux-grown synthetic rubies using the Kyropoulos process have been treated by inducing rutile "silk" similar to those found in the natural untreated rubies. The treatment is irriversible, permanent and detectable by experienced gemologists. Some of these stones to 3 carat size are already in the USA market and sold without disclosure. Ted Themelis will be making a presentation on the topic among related issues during the upcoming IGC (International Gemological Conference) to be held in Moscow in July 2007. Stay tune for more..
