Tourmaline
brings tranquillity and serenity into your life.
Color: Tourmaline comes in many colors
such as blue, yellow, pink, red, black, green and clear.
Green is from iron, chromium and vanadium, pink from manganese.
Some crystals are pink at one end and green at the other.
Description: Tourmaline
is borosilicate mineral of complex and variable composition. Tourmaline
is very abundant and has the best-developed crystals in pegmatites
and in metamorphosed limestones in contact with granitic magmas.
The colored varieties, when transparent and free from flaws, are
cut as gems. Transparent crystals of tourmaline are dichroic -
the depth of color varies as the crystal is turned in the light.
Another peculiarity of tourmaline is that crystal when heated
acquires an electric charge and attracts small objects such as
hair or small pieces of paper. Rubbing crystal imparts a similar
charge.
The name's origin: Tourmaline
came from the Sinhalese name of turmali or tormally (multicolored).
Birthstone: Tourmaline
along with opal are birthstones of Libra (Balance): Sept. 23 -
Oct. 23.
Wedding anniversary: Multicolored
Tourmaline is the anniversary gemstone for the 8th year of marriage.
Varieties: Three types
of tourmaline, distinguished by the predominance of certain elements,
are usually recognized:
iron tourmaline (schorl), black in color;
magnesium tourmaline (dravite), brown;
alkali tourmaline, which may be pink (rubellite), green (Brazilian
emerald), or colorless (achroite).
Care and treatment: As
with all gems, protect tourmaline from scratches and sharp blows.
Avoid drastic temperature changes. Do not clean tourmaline in
a home ultrasonic cleaner.
From the stone history:
Tourmaline was known by cenuries by the name schrol. Colored crystals
were imported from Sri Lanka at the beginning of the 18th century.
During medieval days tourmaline was thought to heal physical and
mental disorders as well as prevent death. Used as a gem for over
2,000 years.
In addition to its use as a gem, tourmaline is employed in pressure
devices because of its piezoelectric properties. It has been used
in depth-sounding apparatus and other devices that detect and
measure variations in pressure.
The colored crystals of tourmaline are very strongly dichroic--
i.e., they are of different color when viewed in the direction
of different axes. Plates cut parallel to the vertical axis of
a tourmaline crystal allow only the extraordinary ray through;
if two such plates are placed in crossed position, the light is
entirely blocked. A pair of these plates form a very simple polarizing
apparatus known as tourmaline tongs.
Shopping guide: Tourmaline
is beautiful in rings, necklaces, and pendants.
Healing ability: Tourmaline
calms nerves, regulates hormones, fights against genetic disorders.
Tourmaline induces a tranquil sleep.
Schorl relieves arthritis pain, helps fighting heart diseases.
Mystical power: Tourmaline
is said to dispel fear, negativity and grief.
According to legend, the tourmaline of all colors protects the
wearer against many dangers and misfortune.
Rubellite: Is believed to enhance creativity, to increase fertility,
to smooth away passive or aggressive nature.
Schorl: release anxiety, raises altruism, deflects negativity,
neutralizes distorted energies, i.e. resentment and insecurity.

Namibia, Sri Lanka, and USA (southern California, Connecticut,
Maine, New York and Texas). The Isle of Elba is famous for pink
crystals tipped with black which are known as Moors' Heads.
