Conference Highlights

New AGA Conference Addition Sounds Like Science Fiction!

For many years innovators have dreamed of a hand-held technology capable of providing high quality chemical analysis of an unknown object. Science fiction buffs will recall the television series "Star Trek," in which a device was featured that did just this: the fictional Star Trek Tricorder!

Basically, this technology is known today as Raman spectroscopy, the application of which is one of the most important advances in gemological testing. But "hand-held" is not a phrase one associates with raman testing, or at least, not reliable testing. Until now.

We are excited to announce that an illustrious team from the University of Arizona's Departments of Geophysics and Chemistry - including M. Bonner Denton, Robert Downs, and Scott Tilden - along with Elizabeth Yarbrough and Jim Pasmore of Rigaku Raman Technology, have joined the illustrious speakers at this year's Tucson conference on February 1st. They will unveil a new, high performance, hand-held instrument capable of providing many of the desired abilities of Star Trek's Tricorder—instrumentation capable of identifying a wide variety of materials including gems and minerals, as well as treatments!

Conference attendees will learn about the capabilities - as well as the limitations - of Raman in the world of gemology, including such important areas as determining a gemstone's provenance and whether it is of natural or synthetic origin…and how lower prices as well as portable size are opening possibilities never before envisioned.

Natural Tanzanite a Myth?

tanzanite

How many articles and "educational" sites do you see where information about tanzanite tells readers that it's only created by heating brown zoisite to transform it into its vibrant blue color? How many sales people who want to be forthcoming about treatments are quick to point out that tanzanite is "treated" to obtain its lovely blue color? And now, ironically, are you among those who have been accosted by a "knowledgeable" consumer when you talk about "natural color" tanzanite who insists that ALL blue tanzanite is the result of heat treatment and you don't know what you're talking about?

Now is the time to explode the myths, learn the facts, and arm yourselves with what has been learned in the latest research related to natural and treated tanzanite.

Thomas Hainschwang

Thomas Hainschwang will share his latest research findings related to tanzanite and its treatments. Thomas, Director of GGTL Laboratories in the European principality of Liechtenstein and Geneva, Switzerland, a joint venture consisting of the Liechtenstein-based laboratory and Franck Notari's GemTechLab in Geneva, will set the record straight and provide important information about tanzanite – natural and treated material – and distinguishing characteristics.

Dr. Dominic Mok


All the way from Hong Kong—the Jadeite evaluation capital of the global market—comes Jadeite expert Dominic Mok to address the AGA Tucson 2012 conference.  Come and participate as this highly regarded expert shares insight into the exciting world of Jadeite identification and quality factors. This session is a must for anyone following current trends in gemology.

Jade is making headlines, in the press and at auction!

On December 29 in the New York Times, a full page devoted to China Watch ran the headline: "Jade Craze Grips the Market!" And jadeite keeps setting new records at major auction houses and is moving center stage at the world's most prestigious jewelry shows. At the same time, it has also been noted by gemologists and other experts that there is an unusually large quantity of what appears to be exceptionally fine quality jadeite in the current market. Some have commented that it brings to mind the incredible "padparadscha sapphire" that was suddenly appearing too often and was subsequently found to be beryllium diffused...and are wondering about jadeite.

Whatever your knowledge level, you won't want to miss the presentation by Geologist Dominic Mok, MSc, FGA, FGAA, DGA and Director of the Asian Gemmological Institute & Laboratory, Hong Kong. A limited number of Mr. Mok's jadeite color wheels will be distributed to attendees during the conference.
