TOURMALINE
- Gemstones
by The Brazilian Connection
Tourmaline is the most colorful member of the
gemstone
family,
sometimes with alternating colors in the same gem. Tourmalines are gems with
an incomparable variety
of colors. The reason, according to an old Egyptian legend, is that
the tourmaline, on its long journey up from the centre of the Earth,
passed over a rainbow. In doing so, it assumed all the colors of the
rainbow. And that is why it is still referred to as the 'gemstone of
the rainbow' today. There are tourmalines from red to green and
from blue to yellow.
They often have two or more colors. 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. 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 'indicolites', yellowish-brown to dark brown ones as
'dravites' and black ones as 'schorl'.One particularly
popular variety is the green tourmaline,
known as a 'verdite' in the trade. However, if its fine emerald-like
deep 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 2001, another deposit of
"Paraiba" tourmaline was discovered in Nigeria. The
Brazilian and the African stones both get
their beautiful color from copper and manganese. This has been
explained by the theory that South America and Africa were once joined
together, now separated by the result of continental drift. In good
qualities, these gemstones are much sought-after treasures today.Stones with
two colors are known as bi-colored tourmalines, and those with more
than two as multicolored tourmalines.
Slices showing a cross-section of the tourmaline crystal are also very
popular because they display, in a very small area, the whole of the
incomparable color variety of this gemstone. If the centre of the
slice is red and the area around it green, the stone is given the
nickname 'watermelon'.
