MINAS GERAIS
During the last 100 years, 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 deposits in Brazil.
During the 1700s, when Minas Gerais was under Portuguese control, gold and gem mining labor was conducted by slaves taken from the west coast of Africa. This accounts for the large percentage of African descendants who now populate the region.
