Multicolored tourmalines

Tourmalines are true miracles of color. Crystals with only one color are fairly rare, there mostly being various different colors and color nuances in one and the same stone. The spectrum is so varied that the tourmaline family alone would suffice to cater to the gemstone wishes of every woman and every man in a particular color or color combination.

Often, Nature conjures up tourmaline crystals from which gemstones with a particularly subtle multi-coloredness can be cut. You may well ask how that is possible. Tourmalines are mixed crystals of aluminum boron silicate with a complex and changing composition. It is a rather complex mineral group. Even minor changes in composition cause completely different colors. And that is how, on one and the same crystal, although it has grown quite naturally, completely different colors can occur, mostly in elongated columns one above the other, as if Nature had piled colored rings one on top of the other. The crystals themselves can be as slim as a knitting needle or as thick as a man's thigh. Some display coloration in which the shades vary only slightly, whilst others have starkly contrasting colors or zones of color. Since tourmaline crystals have often grown in close proximity to one another, their cross-sections can also contain triangles, which are closely joined together and gathered around a nucleus.

Stones with two or more different, well-represented colors are particularly desirable. Depending on their shape and color, these are known in the trade as bicolored and multicolored tourmalines respectively. Some of them also have rather interesting names: if, for example, the crystal is almost colorless and just black at both ends, it is referred to fondly as a 'Mohrenkopf', (a kind of cake popular in Germany). If it was red at one end it used to be called a 'Turk's head tourmaline'. Bicolored tourmalines with a red centre, which changes to green towards the edges, are still referred to as 'watermelons'. If the color zones of the crystal lie on top of one another, the Brazilians call it a 'papageios' or 'rainbow tourmaline'.

The main deposits of tourmalines are in Brazil and Africa. But Nature has also made Man a gift of this beautiful gemstone, always good for a surprise on account of its great diversity of color, at other deposits, for example in Sri Lanka and Madagascar.

Pure individuality

Tourmalines are popular not only in jewelry but also as therapeutic stones. Thanks to their good energetic conductivity and their wealth of minerals, they are said to have an invigorating and fortifying effect. They are uncomplicated to work with and have excellent wearing qualities thanks to their good hardness. Beautiful multi-colored tourmalines are particularly well suited to jewelry of an individual design, for each of these stones is different. More than that, indeed: practically each of the places where this gemstone is found - and it occurs all over the world - has its own color variant. That does make life somewhat difficult for the cutter if he has to look for several stones of the same color; in fact even two stones cut from the same raw crystal often differ in color. But then that is the charm of the tourmaline, and especially that of the multi-colored tourmaline. Today, gemstones of this kind are very popular. The knowledge that one is practically certain to be looking at a unique gem has an inspiring effect on goldsmiths and designers alike, so they look forward to working with this stone and making it the heart of some attractive, individual jewelry creation.
