AGA Conference in Tucson
The Accredited Gemologists Association is holding a gemological conference Feb. 4 during the Tucson gem and mineral shows. The conference takes place 9 a.m.-5:30 p.m. at the Marriott University Park in Tucson, AZ.
Morning sessions will include a focus on the production of synthetic diamonds as well as diamond treatments, while afternoon sessions will focus on the latest information about bulk/lattice diffusion treatments in corundum.
Synthetic Diamond Production, 9-10 a.m.
This panel features synthetic diamond producers who will describe their products, including details about production, product descriptions, pricing structures and treatments as well as future plans. The first panelists are Carlos Valeiras of Gemesis, Robert Linares of Apollo Diamonds, Alex Grizenko of Lucent Diamonds and Thomas Chatham of Chatham Created Gems.
Identification Techniques, 10:15-11:15 a.m.
Representatives from major gemological laboratories will discuss lab techniques, identification characteristics and new instrumentation. Panelists include Branko Deljanin of EGL USA, Henry Hanni of SSEF Swiss Gemmological Institute, Thomas Hainschwang of Gemlab in Lichtenstein and Shane McClure of the Gemological Institute of America Gem Trade Lab.
Diamond Treatments, 11:30 a.m -12:30 p.m.
Laboratory representatives from around the world will include information about identification techniques and detection as well as the instruments that are being used. Panelists include Branko Deljanin of EGL USA, Henry Hanni of SSEF Swiss Gemmological Institute, Thomas Hainschwang of Gemlab in Lichtenstein and Shane McClure of GIA GTL.
Hands-On Diamond Session, 1:30 p.m. 3:15 p.m.
Participants will be able to closely examine synthetic diamonds from the major producers. Participants will be able to put to use identification techniques they learned in earlier panel sessions.
Bulk Diffusion Treatment of Corundum: An Update, 3:30-4:30 p.m.
Representatives from leading gem labs will relate their latest findings on this topic. Panelists include C.R. Beesley of American Gemological Laboratories, John Emmett of Crystal Chemistry, Ken Scarratt of the American Gem Trade Association Lab, Christopher Smith of GIA and Ted Themelis, author and gem treater.
Hands-On Workshop, 4:30-5:30 p.m.
This will be a chance for participants to see and examine samples of the bulk diffused corundum.
There will also be a gala dinner-dance and award ceremony following the conference, from 7-9 p.m. at the Marriott University Park. Tickets are $35. RSVP to Antoinette Matlins at (800) 962-4544 or AMatlins@aol.com.
