More about Tourmaline:
Tourmaline came from the Sinhalese name of turmali or tormally (multicolored). For centuries it was known by the name Shrol. Colored crystals were imported from Sri Lanka at the beginning of the 18th century. Used as a gem for over 2,000 years.
Tourmaline is borosilicate mineral of complex and variable composition. The colored varieties, when transparent and free from flaws, are cut as gems. 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. 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.
Comes in various colors and hues. Balances, protects, calms, gives self- confidence and cheerfulness. Useful for meditation. Protects wearer against misfortune and anemia. Prevents lymphatic disease. Promotes clear verbal expression, dissolves mental friction, emotional constriction. Carries a high electrical charge and if rubbed briskly one end becomes positive and one negative, the energy can then be directed wherever peaceful energy is required. Watermelon/Pink Tourmaline is a heart balancer.
Tourmaline is found in Africa, Brazil, Madagascar, Mexico, Myanmar, 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.
