The more than 60 scientists, engineers, gemmologists and technicians of GIA\u2019s global research team met November 1-3 at the Institute\u2019s world headquarters in Carlsbad, California, USA. Joined by members of the GIA Board of Governors and several prominent consulting scientists, the participants discussed and reviewed recent extensive discoveries that underpin GIA\u2019s education programs, laboratory services and instrument development.<\/p>\n
\u201cRigorous independent research is at the centre of GIA\u2019s activities and is vital to our consumer protection mission and our services for the trade,\u201d said Tom Moses, GIA Executive Vice President and Chief Laboratory and Research Officer. \u201cAs the focus of our efforts has progressed from gemmological discoveries and investigative techniques to incorporate ever-more advanced technologies, the scope of this meeting has expanded to include artificial intelligence, advanced statistical modelling, new custom and proprietary instruments, and advancements in automation.\u201d<\/p>\n
Participants in the three-day conference discussed the latest research advancements in natural and laboratory-grown diamonds, coloured stones, pearls and instrumentation.<\/p>\n
The discussion of natural and laboratory-grown diamonds included observations of the unique inclusions in diamonds, fluorescence and colour-zoning in some coloured diamonds, advancements in laboratory-grown diamonds and the continuing challenges of research into diamond origin determination.<\/p>\n
Regarding coloured stones, the researchers delved into the geochemistry of various species, the use of advanced techniques to detect diffusion treatments and the gemmological characterization of emeralds from North Carolina, United States. Pearl topics included the challenges in identifying unusual cultured pearls and using trace\u2010elemental analysis and machine learning to support pearl origin identification.<\/p>\n
The discussion of technology included advanced imaging systems to support the grading of high-clarity diamonds and the development of a fancy shape cut grading system, and advancements in GIA\u2019s efforts to develop an automated instrument-based diamond grading system for many categories of diamonds.<\/p>\n","protected":false},"excerpt":{"rendered":"
