Paraiba tourmaline - One of the most sought-after gems in the world

Paraiba tourmalines have become one of the most popular gemstones in the world. First discovered in the 1980s by Heitor Dimas Barbosa - who spent years digging in the hills of the Brazilian state of Paraiba, Paraiba tourmaline's vivid glow cannot be found in any other gemstone.

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.
