The Journey of Gemstones - From Mine to Market

This collection represents the world’s first anthology of field gemology, distilled from 12 immersive expeditions. With over 90% of the entries written within the past year, this volume offers an authentic portrayal of mining landscapes and an elite perspective on the upper echelons of the industry supply chain. From the diverse local customs and unique geological environments of global mines to the intrinsic properties of colored gemstones, these stories capture the vibrant world of gemstone origins through multiple lenses. The Guild Field Gemology expeditions encompass the entire colored gemstone supply chain, from mine to market. The Guild Institute of Gemology is dedicated to leading domestic professionals to mining regions and trading hubs worldwide for study tours, connecting them directly to the "source of knowledge" through our Field Gemology Program. In many of these expeditions, we bring students directly to the heart of gemstone production. Participants join the Guild Institute in collecting mine samples and conducting literature research, embarking on the kind of aspirational adventures most only dream of. To date, GUILD’s footprint has spanned Colombia, Brazil, Mozambique, and Zambia, fostering connections with leading experts across the global industry. Through this book, you will find intellectual resonance with top international miners and buyers, taking in breathtaking landscapes while mastering the pulse of the upstream supply chain.
