Minas Gerais is the powerhouse of Brazilian gemstone production and one of the most prolific gem-producing regions on the planet. The state's pegmatite fields yield an extraordinary diversity of stones including world-class tourmalines, aquamarines, imperial topazes, emeralds, kunzites, and morganites. The region around Teófilo Otoni is a global hub for colored gemstone trading, and the Ouro Preto area is the exclusive source of imperial topaz.
历史
Gemstone mining in Minas Gerais began during the Portuguese colonial era in the 18th century when gold prospectors discovered diamonds and colored stones. The name 'Minas Gerais' literally means 'General Mines', reflecting its long history as Brazil's mining heartland.
