Sturdy ancient coin studs have a ring from which hangs a stunning square gem

The hand cut facets glow with a rich emerald hue - these square cut Paraiba Tourmaline crystal gems really are a lovely shade of vivid watery sea green/blue - it's signature internal incandescent glow is caused by trace amounts of copper and manganese

First discovered in 1989 in the Brazilian state of Paraíba by miner Heitor Dimas Barbosa

While the original Brazilian mines have mostly been exhausted, newer deposits were later discovered in Mozambique and Nigeria

Gem - 20 x 20mm

Unique piece
