 | The vivid glow that distinguishes the Paraiba tourmaline, also known as cuprian elbaite is unique. A product of the trace element copper, colours range from startling turquoise to majestic blue-green, but it is the incandescent glow that appears to light up the stone from within that makes Paraiba tourmalines incomparable to any other gem.
In 2003 Paraiba tourmalines were discovered in Mozambique and Nigeria. Paraiba-like in every way, with only minute chemical differences to those unearthed in Brazil, they are often found weighing five carats or more. |  |
