PARAIBA
Discovered by Heitor Dimas Barbosa, an enthusiast miner, these neon blue tourmalines were first introduced to the world in the 1980s. They can only been found in copper rich areas such as Brazil, Nigeria and Mozambique.
Tourmalines from Mozambique have widest ranges of colours and this alluring neon blue colour is due to traces of copper and they are commonly known as Paraiba tourmalines. Its unique brilliance occurs because of the refraction of the light within the stone – the light is reflected several times, which intensifies the colour and creates the neon glow effect.
