Raw Paraiba Tourmaline #2
Brazilian Paraiba (Cuprian Elbaite variety) Tourmaline: A rare form of Tourmaline called Cuprian Elbaite Tourmaline from the Paraiba region of Brazil. Paraiba Tourmaline is a complex aluminium borosilicate with a high copper content which results in the characteristic “electric blue” or turquoise colouration. Cuprian Elbaite Tourmaline is also described as “Neon Tourmaline” due to the vivid “neon” blue colouration. It is often found in combination with Pink (Elbaite) Tourmaline and is quite rare.
To put their rarity into perspective, there is only one Paraiba tourmaline mined for every 10,000 diamonds.
