AGA announces 2018 Antonio C. Bonanno Award for Excellence in Gemology winner


Dr. William (Bill) Hanneman to receive prestigious award

AGAThe Accredited Gemologists Association (AGA) Bonanno Award recognizes those who have made significant contributions to the gemological field. Recipients of the award are selected by a majority vote of the AGA membership. 

Dr. Hanneman’s contributions to the gemological community are many. From education to his various innovative tools, Bill Hanneman’s body of work is of profound benefit to gemology. “Dr. Hanneman has dedicated decades to providing gemologists with practical solutions to many of gemology’s big challenges. It would difficult to think of anyone more deserving of this recognition,” said AGA President Stuart Robertson.

Hanneman exemplifies what the Bonanno Award represents: gemological expertise and excellence in gemological practice, research, and education, and a dedication to sharing gemological knowledge through formal teaching and professional collaboration. Dr. Hanneman has authored a number of books, including: “Guide to Affordable Gemology”, “Pragmatic Spectroscopy for Gemologists”, “Diamond Cut Grading Simplified” and “Naming Gem Garnets”, all of which were motivated by Bill’s desire to make gemological information affordable and thereby assessable to anyone interested in exploring the subject.

Hanneman’s many tools are notable because they filled a gap for something portable, affordable and practical. They include the Diamond Eye, a reflectivity meter providing RIs for gems with RI values over 1.80; the Diamond Eye provided readings for such gems as diamond and synthetic moissanite, CZ and other diamond look-alikes. Another Hanneman tool provided not only an RI, but birefringence and dispersion for faceted gems, with RI values up to 2.37 (and without the need for toxic liquids). His color filters, developed in collaboration with Alan Hodgkinson, provided quick and easy pre-screening ID, and his specific gravity balance was the first to provide direct readings, even for gems weighing under one carat. 

Dr. Hanneman’s work parallels that of Mr. Bonanno’s distinguished career, it’s a life-long body of exceptional work inspired by a desire to share his work and knowledge with gemologists everywhere, students and professionals alike. His contributions to the field of gemology have had a tangible impact on gemologists, universally.

Previous recipients of the AGA Antonio C. Bonanno Excellence in Gemology Award include: Al Gilbertson, Dr. Cigdem Lule, Dr. Thomas Hainschwang, Dr. John Emmett, Dr. Emmanuel Fritsch, Thom Underwood, Stuart Robertson, Richard Hughes, Christopher Smith, Dr. James Shigley, Shane McClure, Richard Drucker, Alan Jobbins, Antoinette Matlins, Dr. Henry Hanni, The late G. Robert Crowningshield, John Koivula, C. R. Beesley, and Alan Hodgkinson.

Bonanno Award for Excellence in Gemology will be presented at AGA’s Gala Dinner Dance at the conclusion of its Tucson Conference, Wednesday, January 31, 2018, from 6:30 - 11:00 PM, at the Tucson University Park Hotel.
