Paraíba Tourmaline

Real mineral · legendary · Na(Li,Al)₃Al₆(BO₃)₃Si₆O₁₈(OH)₄

Elbaite tourmaline coloured by copper and manganese, producing an unparalleled neon blue that appears to glow from within under any light source. First discovered in 1987 in Paraíba, Brazil after years of excavation by a single miner. The original Brazilian deposit is now essentially exhausted. Consistently fetches higher prices per carat than diamonds of equivalent size.
