GIA names research keynote speakers for Symposium 2011


(CARLSBAD, Calif.) – The Gemological Institute of America (GIA) has announced the six speakers slated to deliver keynote presentations for the research track of Symposium 2011: Advancing the Science and Business of Gems.

Registration is now open for the May 29–30 conference, which will be held at GIA’s world headquarters in Carlsbad.

The six keynote presentations support the four major sessions for the research track:

  • “Diamond Identification” – Dr. Mark Newton, of the University of Warwick, U.K, will share his expertise on treated diamond detection.
  • “Gem Localities and Formation” – Dr. Gaston Giuliani, of the French Center for Petrographic and Geochemical Research, will examine the geology of colored stone deposits; and Dr. Thomas Stachel, of the University of Alberta, will discuss Canadian diamond geology.
  • “Colored Stones and Pearl Identification” – Dr. Ahmadjan Abduriyim, of Tokyo’s Gemmological Association of All Japan-Zenhokyo, will address geographic origin determination; and Ken Scarratt, managing director of GIA Southeast Asia and director of the GIA Laboratory in Bangkok, will discuss pearl identification.
  • “New Technology and Instrumentation” – Dr. George Rossman, of the California Institute of Technology, will offer insight into advanced gem characterization.

Additional research track speakers will be chosen from among abstracts submitted to the conference organizers. Abstracts were also submitted for the poster session. The deadline to receive abstracts for participation in Symposium passed in January.

Keynote speakers for Symposium 2011’s business track, which will run parallel to the research sessions, will be announced at a later date.

Symposium 2011 will commemorate the 80th anniversary of GIA. The event celebrates the Institute’s commitment to serving the public and trade through research, education, gemological laboratory services and instrument development.

Capacity will be limited for Symposium 2011; early registration is encouraged. For information on attending or participating as a speaker or poster presenter, visit www.symposium2011.gia.edu or e-mail This email address is being protected from spambots. You need JavaScript enabled to view it..
