Mozambique Paraiba Tourmaline has become a worldwide sensation, largely in part to its sensational turquoise coloring and distinct composition. Mother Nature's secret formula for Paraiba tourmaline includes copper, an element unique to this variety to tourmaline.
Paraiba tourmaline is a striking gemstone known for its unique glow that has been described as "neon" and "electric." This precious stone has only been found in copper-rich areas of Brazil, Nigeria and Mozambique. Mining this stone is difficult; Paraiba tourmaline is mined mostly by hand with manual tools. The use of dynamite has been discouraged because it damages the crystals. The German Foundation for Gemstone Research found that Paraiba tourmaline has a gold content of 8.6 parts per million (ppm), significantly higher than the earth's crust at 0.007 ppm. However, it is the copper found within its chemical composition that gives Paraiba tourmaline its glowing turquoise pigment. Normally tourmaline gets its color from iron, manganese, chrome or vanadium, and copper has not been found in any other form of tourmaline than Paraiba. Tourmaline, when heated or rubbed, creates an electrical charge becoming a magnet that attracts lightweight materials. Almost all tourmaline has been heat treated for color enhancement, including Paraiba tourmaline.
Brightly colored Paraiba tourmaline deposits were first discovered in 1989 in the Brazilian state of Paraíba by gem miner Heitor Dimas Barbosa. Following the depletion of the Brazilian mines, a deposit was discovered in the African nation of Mozambique in 2003. We source our Paraiba tourmaline from mines in Mozambique. Unlike Brazilian stones, Mozambique Paraiba Tourmaline contains fewer inclusions and can be found in larger sizes.
