Tourmaline is also known as the ‘gemstone of the rainbow’, the word tourmalines means something like ‘stones with mixed colors’ that refer to the color spectrum of this gemstone. There are tourmalines from red to green and from blue to yellow. They often have two or more colors and there are tourmalines which change their color when the light changes from daylight to artificial light, and some show the light effect of a cat's eye. No two tourmalines are exactly alike. With an endless number of faces, and for that reason it suits all moods. In particular, it is the gemstone of love and of friendship. In order to understand this kind of mystery gemstone with its variety of color, tourmalines are mixed crystals of aluminum boron silicate with a complex and changing composition and the mineral group is a fairly complex one. Even slight changes in the composition cause completely different colors. Crystals of only a single color are fairly rare; indeed the same crystal will often display various colors. And the trademark of this gemstone is its great wealth of color, but also depending on the angle from which we look at it, the color may be different or more or less intense. It is always at its most intense when viewed looking toward the main axis. This gemstone has excellent wearing qualities and is easy to look after, for all tourmalines have a good hardness of 7 to 7.5 on the Moths scale. So the tourmaline is an interesting gemstone in many ways. It is quite interesting that the individual color variants have their own names. A tourmaline of an intense red is known as a 'rubellite', but only if it continues to display the same fine ruby red in artificial light as it did in daylight. If the color changes when the light source does, the stone is called a pink or shocking pink tourmaline. Blue tourmalines are known as 'indigolites', yellowish-brown to dark brown ones as 'dravites' and black ones as 'schorl'. The last mentioned, mostly used for engravings and in esotericism, is said to have special powers with which people can be protected from harmful radiation. One particularly popular variety is the green Tourmaline, known as a 'verdelite' in the trade. However, if its fine emerald-like green is caused by tiny traces of chrome, it is referred to as a 'chrome tourmaline'. The absolute highlight among the tourmalines is the 'Paraiba tourmaline', a gemstone of an intense blue to blue-green which was not discovered until 1987 in a mine in the Brazilian state of Paraiba. In good qualities, these gemstones are much sought-after treasures today. Since tourmalines from Malawi with a vivid yellow color, known as 'canary tourmalines', came into the trade, the color yellow, which was previously very scarce indeed, has been very well represented in the endless spectrum of colors boasted by the 'gemstone of the rainbow’. The tourmaline has even more names: stones with two colors are known as bicolor tourmalines, and those with more than two as multicolored tourmalines.
