Copper-bearing tourmaline weighing 75.20cts, from Mozambique
|A product of the trace element copper, colours range from turquoise to blue-green. Good quality Paraiba from Brazil over three carats is very rare. Authentic Brazilian Paraiba tourmalines can achieve five figures per carat.|
In 2003, a wave of luminous green-blue tourmalines entered the market, mined in the copper-rich mountains of Mozambique and Nigeria. They are Paraiba-like in every way, with only minute chemical differences to those unearthed in Brazil.
