1.21ct Green Brazilian Tourmaline Ecut 9x4mm Loose

Discovered in the Batalha mine in Paraíba, Brazil, in the late 1980s by Heitor Dimas Barbosa, copper-bearing tourmalines display a glowing neon blue-green or mint-green color caused by trace elements of copper and manganese. Brazilian-origin stones from this find are among the rarest and most expensive in the world.
