First discovered in Brazil, Paraiba Tourmaline can now be found in only two other localities in the world: Nigeria and Mozambique. Paraiba Tourmaline is defined by GIA and Gubelin Labs by its trace elements of copper, the key ingredient to the stone's famous neon-blue color. Although many of the Brazilian deposits have been all but exhausted, the price and demand for this rare collectible gemstone continue to rise.
