The tourmaline is a unique miracle of colour. The gemstone comes in green, red, blue, yellow, but there are also colourless specimens and black ones.

Often two or more colours are found in a single tourmaline crystal. Also rare and very highly esteemed are tourmalines which appear to change their colour and cat's eye tourmalines. Having said all that, green is regarded as the classical tourmaline colour. If you ask a gemstone merchant about a tourmaline, green, in most cases, is the first colour he will think of.

However, even among the green tourmalines there is a broad spectrum. Some of them are very light, others so dark that the green colour can only be recognised when the stone is held against the light. There are green tourmalines in fine leek hues, but also in intense yellowish-green, olive green and brownish-green nuances. And there are especially wonderful tourmalines in the range from blue-green to dark bottle-green.

These, indeed, are its best colours. They are rare and much sought-after. Green tourmalines are very popular as precious stones among women, but many men like wearing them too.
