Emerald rough from the Belmont mine in the Itabira region of Brazil’s Minas Gerais state
Dubai—Grupo Belmont will start selling its Brazilian rough emeralds via tender, and its first will be through brokerage and consultancy firm Bonas Group this spring.

The rough emeralds are mined at Grupo Belmont’s famous Belmont mine located in the Itabira region of the Minas Gerais state in Brazil. The source was discovered in 1978, and today is one of the most technologically advanced colored gemstone mines in the world.

When asked how many carats will be offered during the sale, a Bonas spokesperson said they don’t have a final volume number yet, noting only they expect it to be “substantial,” with the goods mined predominantly in 2020.
