Blue Tourmaline Earring
What's in a name?
If you plan on buying green tourmaline gemstone jewellery, then there are a incorporate of confusing facts that you need to take note of. Green tourmalines are named whether Brazilian or African, however this does not automatically mean that it has been mined there. Instead it refers to the colour. It used to be the case that bottle-green tourmalines only came from Brazil and blue-green tourmalines came from Africa. This is no longer the case, however they are still referred to as Brazilian or African, even if this is not where they were mined. Brazilian tourmalines are also called Verdelite.
The green colour honestly comes from other materials which are found in trace amounts. For instance, you may come across "Chromium-Tourmaline" which is a rare emerald-coloured tourmaline which has traces of Vanadium and Chromium and is found in Tanzania.
Green tourmaline stones can be found in a estimate of locations throughout the world including Afghanistan, Mozambique, Namibia, Nigeria and Pakistan and are not rare. however looking good ability large stones are very rare and the price incompatibility between large stones and small stones can be a lot more than you may expect compared to other gemstones.
Scientific Marvel
As well as being a very gorgeous stone, scientist are amazed by its "pyro-electricity" properties. What does that mean? Pryo comes from the Greek meaning "fire". If this gem is heated it becomes electrically charged. When the stone is cooled it has a determined charge at one end and a negative charge at the other.
Tourmaline also shares an fascinating asset with rock crystal. The stone is put under pressure to charge, when the pressure is removed the charge changes and the stone begins to oscillate.
Green tourmaline is the second most costly after blue indicolite. The rarest colour of tourmaline is colourless however it is also the cheapest to buy.
