Quarterly evening sessions at GIA in New York

NEW YORK – Oct. 1, 2019 – GIA presents a dynamic and informative series of talks, “GIA New York Science Talks Series,” where GIA researchers will share ground-breaking discoveries related to gemology – including natural diamond formation, what diamonds tell us about Earth’s deep mantle, laboratory-grown diamonds and more. The quarterly talks are free and open to the public. For more information and to register for the first talk on Oct. 30, visit
“GIA New York Science Talks Series” gives guests the opportunity to learn about cutting edge developments in gemological research and ask questions of leading researchers. The hour-long evening sessions begin at 5:00 p.m. at GIA’s education campus on the 8th floor of the International Gem Tower at 50 W 47th Street, New York, NY 10036. Refreshments will be served.
Four initial sessions are planned. The dates and topics are subject to change:

  • Oct. 30, 2019: GIA Research Scientist Dr. Evan Smith shares his breakthrough research on remarkably large, high-clarity diamonds and what they reveal about Earth’s geology.


  • Feb. 19, 2020: GIA Research Scientist Dr. Karen Smit will present research on what natural diamonds indicate about continent formation.


  • May 2020: GIA Research Scientist Dr. Chunhui Zhou uncovers what oxygen isotopes in pearls tell us about paleoclimate.


  • August 2020: GIA Postdoctoral Research Associate Dr. Chloe Peaker talks about transition metals causing gemstone and diamond color.

“With research being the foundation of GIA’s expertise and activities – including laboratory services, education and instrumentation – we are delighted to offer these informal and informative talks at our campus on 47th Street to give the public, students and members of the trade a chance to hear first-hand about GIA’s discoveries and the mission of our research,” said Tom Moses, GIA executive vice president and chief laboratory and research officer.  
GIA leads the industry in gemological research by coupling advanced research with the detailed examination of tens of thousands of diamonds and colored stones that come through the laboratory each year. GIA research aims at responding to rapidly changing gem treatments and new gem materials, as well as deepening the world’s understanding of gemology.

About GIA

An independent nonprofit organization, GIA (Gemological Institute of America), established in 1931, is recognized as the world’s foremost authority in gemology. GIA invented the famous 4Cs of Color, Clarity, Cut and Carat Weight and, in 1953, created the International Diamond Grading System™ which is recognized around the world as the standard for diamond quality.
Through research, education, gemological laboratory services and instrument development, the Institute is dedicated to ensuring the public trust in gems and jewelry by upholding the highest standards of integrity, academics, science and professionalism.
