Tourmaline is a virtually unique colour miracle. Crystals displaying
just one colour are quite rare, usually one and the same crystal
does in fact show various shades and colours. Thus the Tourmaline
family alone has sufficient members to supply all the whims of man
and woman concerning colours: the range is almost unlimited.
Nature creates very special Tourmaline crystals which will then be
cut into sophisticated multicoloured gemstones. You would like to
know how this is possible? Tourmalines are mixed crystals of complex
aluminium boro-silicates in various manifestations. It is indeed
quite a complex group of minerals. Even small changes in composition
will result in completely different colours. Thus it is possible
that in one and the same naturally grown crystal there will appear
completely different colours, usually arranged in longitudinal
columns on top of each other, just as if Nature had put coloured
rings on top of each other. The crystal a such may be as small as a
knitting needle or as thick as a thigh. Some will show only slightly
shaded colour fields, while others display contrasting colours and
clear colour zoning. And since Tourmaline crystals are often grown
into others, a cross section might even show tightly joined
triangles arranged around a core.
What makes a Watermelon a precious object?
coveted are such stones which show two or more strong colours.
Depending on shape and colour, these Tourmalines are traded as
Multicoloured or Bicoloured specimen. Some have earned quite
interesting names, for example, an almost colourless crystal with
black end is called a "Maur’s Head” or "Moor’s Head”. If the tip is
red, then this used to be called a "Turk’s Head Tourmaline”.
Bicoloured Tourmalines with a red core that changes into green
around the perimeter is still called "Watermelon Tourmaline”. And if
the colour zones are arranged on top of the other, than in Brazil
this is called a "Papageios” or a "Rainbow Tourmaline”.
The most important occurrences for Tourmalines are situated in
Brazil and in Africa. But also from other gemstone occurrences all
over the world – like, for example, from Sri Lanka or Madagascar -
Nature’s gifts are brought to us in the form of this beautiful
gemstone, which because of its enormous variety of colour will keep
on surprising us.
The epitome of individuality
Tourmalines are popular as jewellery stones but also as healing
stones. Due to their good energetic conductivity and their wealth of
mineral elements they are supposed to have recreational and
constructive effects. They are uncomplicated to work with and
because of their good hardness are excellently suited for everyday
wear. Beautiful multicoloured Tourmalines are best suited for highly
individual jewellery designs, since each stone is different from the
other. In addition to this: almost each occurrence of this worldwide
existing gemstone will display a specific colour variation. However,
this fact makes it difficult for cutters to find matching stones in
one and the same colour, for even two stones cut from the same rough
mother crystal will often show different colours. But it is just
this characteristic which makes Tourmalines so attractive,
especially the multicoloured ones. Such gemstones are very much in
demand at present. The fact that each stone is a unique original
inspires goldsmiths and designers, who love to integrate this
precious stone into their individual jewellery creations as the
