GIA Pioneer and Leading Librarian Dona Dirlam Retires after 38 Years

The Gemmological Institute of America (GIA) has announced that after 38 years Library and Information Centre Director, Dona Dirlam, has retired, leaving behind a legacy of excellence and a pioneering approach to digitisation of gemmological knowledge.  

Having been with GIA since 1979, Dirlam will be remembered for her direct influence in both establishing and growing the Richard T. Liddicoat Gemmological Library and Information Centre, renowned for being a leading resource hub for gemstone and gemmology students and professionals. Dirlam's successor in the role will be Robert Weldon who has been the Manager of Photography and Visual Communications at GIA since 2006.

Holding a Master's of Science degree in Geology and Geophysics from the University of Wisconsin (Madison), Dirlam began her career as an earth sciences teacher before pursuing her passion for gems and minerals at GIA's campus in Santa Monica. She began her tenure at GIA as a staff gemmologist after completing her GIA Graduate Gemologist (GG) diploma.

She swiftly became a research librarian in 1980 after Liddicoat himself offered her the chance to expand the Institute's library. Dirlam was named Director of the Carlsbad-based library in 1995, co-authoring articles for GIA's quarterly professional journal Gems & Gemology (G&G), as well as presenting numerous lectures on a plethora of historical topics.

Throughout her time at GIA, Dirlam was commended for her ongoing commitment to providing greater availability and access to GIA's rare book collection. Her efforts led her to digitise the rare holdings of the Institute, facilitating free and open access for the gem industry.

As a result of her work and dedication, the once-modest GIA library has expanded its collection to include over 57,000 books, 700 journal and magazine titles, 1,800 video recordings, 198,000 digital images and more than 300 scanned books, now available to read here.

Dirlam received the Outstanding Gemmologist Award from the Association of Women Gemmologists in 1989 and GIA's Staff Member of the Year award in 1991. Additionally, she was presented with the Richard T. Liddicoat Distinguished Achievement Award in 2004; the Accredited Gemmologists Association Lifetime Achievement Award in 2015; and the Women's Jewelry Association's Award for Excellence in Special Services in 2016.

Susan Jacques, President and CEO of GIA said: "Dona's ground-breaking efforts on behalf of the Institute's research, education, and outreach capabilities have kept GIA at the forefront of gemmological scholarship."

On her innovation and contributions to the industry, Dirlam commented: "Cultivating our library's collection and creating accessibility for the public has been the library's main goal. It takes dedicated individuals to handle the projects that come through our door and for that I am honored to have worked with a phenomenal team. What we have accomplished in the past decades will continue under the leadership of Robert Weldon."

Since Dirlam's retirement in late August, Weldon has assumed his responsibilities as Library Director; intending to continue the legacy left by Dirlam by expanding the GIA collection and further enhancing its accessibility to students, the trade and the public.

Commenting upon his new position, Weldon said "“Dona had such an influence on my life and has trained me over the years to have a great respect for the valuable books of which our team is custodian. These are exciting times ahead with such transformation in the library field. The questions of how we deliver information in this digital age, and how we reach and stimulate the minds of our current and future gemmologists, will be at the core of my focus."

Rare 4.23ct Fancy Pink-Purple Diamond Hits $1.1m at Auction

An exceptionally rare and extraordinary 4.23 carat fancy pink-purple oval-cut diamond ring sold for $1.1 million at Bonhams Rare Jewels and Jadeite Auction in Hong Kong on November 27. 

Created by Taiwanese jewellery designer Cindy Chao, the beautiful dress ring caused a flurry of bids among local and global collectors of rare jewels and gemstones, eventually fetching more than HK $9,100,00.

The piece is considered the star of Chao's Ribbon Collection, with the 4.23 carat fancy colour diamond surrounded by ribbons of precious metal set with round brilliant and cushion-cut diamonds.

Highlights from the auction also included a rare 10.02 carat 'no-oil' cushion-shaped Columbian emerald ring set with trillion-cut diamond shoulders. The ring, reaching well above its estimate, sold for $781,976 (HK$6,100,00).

"Overall the sale was very positive with strongest interest from local and global collectors in white colourless diamonds, fine gemstones and rare jewels," commented Graeme Thompson, director of jewellery at Bonhams Asia. "Bids came in from around the world including Pan-Asia, the Middle East, Europe and America reflecting Hong Kong as an international auction market hub."

The next fine jewellery auction by Bonhams auction house will take place on December 7, 2017, in London.

Dr. William Hanneman Named 2018 AGA Antonio C. Bonanno Award Recipient

The Accredited Gemologists Association (AGA) has announced that Dr. William (Bill) Hanneman is to be awarded the 2018 AGA Antonio C. Bonanno Award for Excellence in Gemology.

Selected via a majority vote of members of the Association, the coveted AGA Bonanno Award is presented to an individual who has made a significant contribution to gemmology through their work and research.

Acknowledged for his continuous support of the gemmological community, Dr. Hanneman has had a profound impact on the industry through his practical solutions, research and exceptional professional practise. From his numerous collaborations and formal teaching in the field, AGA President Stuart Robertson affirms that Hanneman exemplifies the excellence that the Bonanno Award represents.

Robertson comments: "Dr Hanneman has dedicated decades to providing gemologists with the practical solutions to many of gemology's big challenges. It would be difficult to think of anyone more deserving of this recognition."

Throughout his professional career, Dr. Hanneman has played a vital role in sharing knowledge and information to ensure it is universally assessable to all gemmologists. Hanneman has also authored a number of successful books including, Guide to Affordable Gemology, Pragmatic Spectroscopy for Gemologists, Diamond Cut Grading Simplified and Naming Gem Garnets.

Dr. Hanneman's work has had a positive impact on gemmologists, both students and professionals alike, especially thanks to the portable, affordable and practical tools he created in response to industry need. They include the Diamond Eye, a reflectivity metre providing RIs for gems with RI values over 1.80. 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.

Previous recipients of this AGA award include: AL Gilberston, Dr. Cigdem Lule, Dr. Thomas Hainschwang, Richard Drucker, Alan Jobbins, Antoinette Matlins, Stuart Robertson, Alan Hodgkinson, Richard Hughes, Thom Underwood and many others. 

The AGA Antonio C. Bonanno Award for Excellence in Gemology will be presented on Wednesday January 31, 2018, 6:30-11:00 PM at AGA's Gala Dinner Dance to finish its Tucson Conference. Held at Tucson University Park Hotel, the award presentation will also include a $2,000 research honorarium funded by the AGA membership and a personalised plaque.
