About this Item
An unmounted Elbaite Tourmaline
the oval-cut Tourmaline weighing 6.97 carats Accompanied by a report No. 07.08.30.10214 from The Gem and Jewellery Institute of Thailand Elbaite tourmalines are found and mined not only in Brazil, but in copper rich areas such as Nigeria and Mozabique. Traces of iron, manganese, chromium and vanadium are responsible for giving Tourmalines their colour, however this is different for Elbaite Tourmaline as it owes its spectacular colour to the presence of copper.
