Dr. John Emmett to Receive the 2014 Prestigious Antonio C. Bonanno Award for Excellence in Gemology
AGA is pleased to announce that renowned physicist Dr. John Emmett is the recipient of the 2014 Antonio C. Bonanno Award for Excellence in Gemology.
The Bonanno Award recognizes those who have made significant contributions to the gemological field.
Dr. Emmett obtained his Ph.D. in physics from Stanford University. From 1975–1988, Dr. Emmett was Associate Director for Lasers at Lawrence Livermore National Laboratory in Livermore, CA. John is considered a world authority on the physics and chemistry of corundum.
Dr. Emmett's contributions to gemological research are numerous. In the 1990s, John became involved with heat treatment of ruby and sapphire and today is the world's foremost corundum enhancement expert. But it is his work in educating traditional gemologists where he has really excelled. For nearly two decades he has cooperated with the former AGTA GTC and the GIA, along with a host of other gemological organizations and individual gemologists.
John was instrumental in unmasking the beryllium diffusion of corundum through a series of experiments that he designed and conducted. He has worked tirelessly since then to train gemologists in modern scientific methods and encourage gemology to move beyond theory to experimentation in the quest to understand the identification and treatment issues facing this industry. This work has been largely self-funded, donating his time and home lab. Because of his work, with its emphasis on experimentation as a fundamental part of the gemological process, gemologists now have a better understanding of the causes of color not just in corundum, but in gemstones across the board. This idea of experimentation as a means to understanding has revolutionized the science of gemology.
John has repeatedly stressed that knowledge is the common property of all humanity and has willingly shared his expertise with that principle in mind.
The Antonio C. Bonanno Award for Excellence in Gemology will be presented at AGA's Gala Dinner Dance at the conclusion of its Tucson Conference, Wednesday, February 5, 2014, from 6:30 – 11:00 PM, at the Marriott University Park Hotel.

An Opportunity to Make a Difference & Increase the "Brilliance" of Future AGA Conferences
The Accredited Gemologists Association (AGA) is offering an opportunity to bring some of the world's most respected scientists and extraordinary gemologists to one of the country's most respected gemological conferences — the Accredited Gemologists Association's Annual Conferences in Tucson and Vegas. One of the founding principles of the AGA has always been to provide opportunities to gain information pertaining to the latest research and their gemological implications, often long before it appears in gemological journals or elsewhere. But many scientific discoveries are made by experts — both inside and outside of the gem industry — who do not live within the United States and who do not normally attend the Tucson shows.

About the Accredited Gemologists Association
Established in 1974 by Antonio "Tony" Bonanno (as alumnae of the Gemmological Association of Great Britain), AGA was envisioned as a network for sharing gemological information and skills. Graduate gemologists of the Gemological Institute of America joined in 1975. The international Accredited Gemologists Association of today proudly counts among our members some of the worlds leading independent gemologists.
The AGA is an independent, international, nonprofit organization dedicated to...
Gemological Education & Research
Identification & Evaluation of Gem Materials
Development of Professional Standards of Analysis, Practice & Ethics
We are an organization of all beliefs and cultures and share a common bond of the love of gemstones. AGA believes in excellence and is dedicated to establishing the highest professional standards of practice.
The AGA Annual Board Meeting will be held in Tucson, the day before the AGA Conference. The AGA Annual Membership Meeting will be held in Tucson, the day of the AGA Conference. Both events are held in the same facility as the AGA Conference.
