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.

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.
