The Los Angeles chapter invites all alumni, industry friends, gemstone enthusiasts and guests to attend a special evening presentation by noted Caltech professor and researcher Dr. George Rossman. Dor. Rossman will lecture on Chromium in Ruby and Emerald.

Dr. Rossman is professor of mineralogy at Caltech, where he has been since receiving his Ph.D. in inorganic chemistry there in 1971. His work addresses problems relating to mineral identification, the origin of color in gems and minerals, and the global repository of water in rocks and minerals. He was an invited participant in the White House conference on conflict diamonds and has been a keynote speaker at several international mineralogical and gemological symposiums. Dr. Rossman is a Fellow of the Mineralogical Society of America and the recipient of their inaugural Dana Medal, as well as the recipient of the Richard P. Feynman Prize for Excellence in Teaching at Caltech and the Friedrich-Becke Medal from the Austrian Mineralogical Society. He is author or co-author of more than 320 articles in the mineralogical and chemical sciences. Additionally, Professor Rossman received the ultimate honor when in 1998, The International Mineralogical Association named a new mineral - Rossmanite – in recognition for his work on the spectroscopy of the tourmaline-group minerals (and many other mineral species). Dr. Rossman served as a member of the GIA Board of Governors in the 1990s and 2000s and is currently a member of the editorial review board for GIA’s Gems & Gemology journal.
