A limited number of conference attendees also will be able to join a one-day preconference field trip to the Pala pegmatite district in San Diego County (separate registration is required).

This year’s International Gemological Symposium, only the fourth in three decades, will attract professionals from every sector of the gem and jewelry trade. For three days, leading researchers and industry experts will address key economic, technological, and geopolitical factors of the industry in the 21st century. The theme, “Navigating the Challenges Ahead,” signals that the gem and jewelry industry is entering uncharted territory. The Symposium will address the major changes that the industry has witnessed at virtually every level.
