Probably the most significant presentation at the 2010 Tucson Gem Show was from Robert James of the International School Of Gemology.
You may remember that Mr James claimed at the 2009 Tucson Gem Show that the recent flood of Red Andesine was instead treated Feldspar...his report started a rumble in the Industry that has resulted in a trip to the "mine" - lawsuits - the discrediting of an Olympic Games collectible gemstone (did you buy the Chinese Andesine Olympic Gems from DSN as natural?)...and now in 2010 Robert James was back with his latest report "Andesine - The Final Chapter".
This event was attended by a virtual who's who of the gemology field, US feldspar miners, luminaries of the international mining industry and some reporters we haven't seen in quite some time...
I am not going to repeat the information - just give you some of the high points.
Have I peaked your interests? If you are interested in seeing how Robert James and the ISG research team came to these conclusions...complete with emails from the Mongolian Mining Office, see below.
A DVD of the presentation is available from the ISG (proceeds will support future research by ISG). To purchase a copy from the ISG click here.
