Tourmalines are found almost all over the world. There are major deposits in Brazil, Sri Lanka and South and south-west Africa. Other finds have been made in Nigeria, Zimbabwe, Kenya, Tanzania, Mozambique, Madagascar, Pakistan and Afghanistan. Tourmalines are also found in the USA, mainly in California and Maine. Although there are plenty of gemstone deposits which contain tourmalines, good qualities and fine colors are not often discovered among them. For this reason, the price spectrum of the tourmaline is almost as broad as that of its color. It is not only designers who love the tourmaline on account of its inspiring variety of color. Scientists too are interested in it because of its astonishing physical qualities, for tourmalines can become electrically charged when they are heated and then allowed to cool.
Then, they have a positive charge at one end and a negative one at the other. This is known as “pyro-electricity,” derived from the Greek word “pyr,” meaning fire. The gemstone also becomes charged under pressure, the polarity subsequently changing when the pressure is taken off. When the charge changes the tourmaline begins to oscillate, similar to a rock crystal but much more pronouncedly. In the fascinating world of gemstones, the tourmaline is very special. Its high availability and its glorious, incomparable color spectrum make it one of our most popular gemstones - and apart from that, almost every tourmaline is unique.
