Emerald Sources of Brazil Sergio Martins, Stone WorldPlay
Mining AreasThe mines in the state of Bahia were among Brazil’s first emerald-producing locations, dating back to the 1960s. They continue to supply large quantities of emerald to the global market. In Bahia, there is a large production of carving, cabochon, bead, and commercial-quality facet-grade material.
In the state of Goiás, the area near the town of Santa Terezinha de Goiás has yielded large quantities of emerald, primarily in smaller crystal sizes.
The mining areas near Itabira and Nova Era in the state of Minas Gerais generate the most consistent and highest-quality supply of Brazilian emeralds. Itabira is the more stable producer, while Nova Era is known for very large emerald crystals. Montebello is one of the largest and most sophisticated mines in Nova Era. Belmont is a modern operation and an important global supplier on a steady basis. The Belmont mine often cuts its own better-quality emeralds, moving it up the value chain into cut goods. Between Belmont and Nova Era mines lies a newer mine, Piteiras. Though currently closed, it could be reopened and become an important source.
In addition to the established emerald mining areas, new production has started in the state of Rio Grande do Norte under the colored stone mine-to-market legend Lorenzo Yih.
