The state of Minas Gerais is one of 26 Brazilian states, located on the western side of the Southeastern Subdivision. The name Minas Gerais ("General Mines") refers back to the 18th and 19th centuries, when large mines produced gold and precious stones in the state. Minas Gerais still produces about 80% of Brazil's precious gems and minerals, including emerald, alexandrite and topaz.
The cities of Governador Valadares and Teófilo Otoni to the north-east, have established themselves as major hubs of the gem-trading industry, due to their proximity to some of the richest gem mines. Minas Gerais is rich in quantities of aquamarine, chrysoberyl, emerald, kunzite, morganite, tourmaline and topaz.
