One hundred Gemological Institute of America (GIA) researchers, leading academics, independent industry experts and GIA Governors and executives met in person and virtually at GIA’s global headquarters in Carlsbad, California, on 1-3 November for the Institute’s 16th annual research meeting. The participants, representing hundreds of years of expertise, reviewed recent findings on a broad range of topics, including geographic origin determination for coloured stones and pearls, new methods for identifying laboratory-grown diamonds and treated gems, advancements in automated diamond grading and the development of specialised gemmological instrumentation and analysis techniques.
Susan Jacques, GIA President and CEO, said, “Extending the world’s knowledge of gemmology is at the core of our important consumer protection mission. GIA is unique in having a talented team of remarkable scientific experts, world-renowned outside advisors and the advanced technology, scientific instrumentation and other resources to support such important work that yields concrete benefits for the public and the trade.”
Tom Moses, GIA Executive Vice President and Chief Laboratory and Research Officer, said, “GIA’s comprehensive research programs are fundamental to our work to ensure and preserve the public trust in gems and jewellery. That trust is threatened by the increasingly sophisticated treatments we see in our identification and grading laboratories. This is why we devote so much effort to advancing and sharing our research.”
The 60-person GIA research team including more than 20 with advanced degrees, four members of the GIA Board of Governors, GIA executives and prominent independent research consultants presented and discussed the extensive research and discoveries that underpin the Institute’s education programs, laboratory services and instrument development.
Presentations included using data science and machine learning to develop robust statistical methods for determining coloured stone origin, new methods to identify laboratory-grown diamonds, detection of new treatments and advancements in developing a laboratory-based automated diamond grading system.
