Paraíba Tourmaline

Variety of elbaite

Legendary · Na(Al₁.₅Li₁.₅)Al₆(Si₆O₁₈)(BO₃)₃(OH)₃(OH)

Elbaite tourmaline coloured neon blue to green by copper, with manganese, a colouring agent in no other tourmaline. It was first found in the late 1980s in the state of Paraíba, Brazil; similar stones came from Nigeria and Mozambique in the early 2000s, and the trade now uses the name for the colour, whatever the origin. Brazilian stones still command the highest prices.
