  Gem conference explores new developments  
 

   
    At GIA's inaugural Gemological Research Conference (GRC), held August 26-27 in San Diego, California, over 700 participants from 32 countries explored the latest technical developments in gemological research. The event was sponsored by Charles & Colvard and held in conjunction with the 4th International Gemological Symposium.

 
 
       The GRC kicked off with a field trip to the Pala pegmatite district. The all-day tour gave 50 participants an informative, hands-on look at three working gem mines in north San Diego County. A second field trip to Pala took place just after the closing of the International Gemological
Symposium.

   
    
In the dual-track speaker sessions, leading researchers delivered 62 oral presentations that addressed the six general topics of the conference, including Geology of Gem Deposits; New Gem Localities: Among the highlights here was a discussion of gem deposits in Afghanistan, and a talk on promising new localities in Madagascar; Gem Characterization Techniques; Diamond and Corundum Treatments; Laboratory Growth of Gem Materials; and General Gemology: Keynote lectures here included an introduction of a new classification scheme for gem corundum based on geologic source type.

       A posters forum saw 62 exhibitors on hand to present their research findings through multimedia displays and one-on-one discussions. Among the poster presentation topics were the mining of pegmatite-related primary gem deposits, ruby and sapphire from Greenland, and the geology of placer gem deposits.

       The conference's co-chairs, GIA research director James Shigley and G&G editor Brendan Laurs, plan to make it a regular event. The next GRC is now scheduled for August 2009. "The response to the GRC exceeded all of our expectations,"said Mr. Laurs. "The dual speakertracks gave conference participants an opportunity to choose the topics that best matched their interests, while the poster session rounded out the program with a wide variety of research applications in contemporary gemology."
