The Bowers Museum in Santa Ana is hosting an interesting lecture on March 19: http://www.bowers.org/index.php/learn/events_details/858

Macro to Micro: Inclusions and Gem Formation
Inclusions in gem materials are generally quite small and most often microscopic. However, some are surprisingly large, and contribute significantly to both the beauty and value of the gems hosting them. John Koivula, Chief Research Gemologist, GIA, world leading authority on inclusions in gemstones, explores such inclusions at the macro and micro levels, and describes how they can also help to define the geological origins of their hosts.
Co-sponsored by the Gemological Institute of America and the Gem and Mineral Society, Los Angeles Museum of Natural History.
