Field Gemology
Experience Gems at Their Origin
Our Field Expedition programme takes gemological education beyond the classroom — straight to the mines, markets, and cutting workshops where the world's most valued gemstones are unearthed and traded.
Guided by experienced gemologists and local experts, participants navigate real mine sites, negotiate in trading markets, and observe cutting operations first-hand, gaining practical insights no textbook can offer.
