ETYMOLOGY: Turmali comes from the english term, meaning approximately "Stone of various colors."

CRYSTAL SYSTEM: Trigonal.

CLASS MINERAL: Ciclosilicatos.

FIELDS: Brazil, Afghanistan, Australia, Burma, India, Madagascar, Zimbabwe, Tanzania, Sri Lanka, Nepal, Zaire, Namibia.

MINERALOGY: The tourmaline originates primarily in plutonitas acids, specifically pegmatite, where forms large crystals. Through the action of gases containing boron, from the magma of the host rock, tourmaline it can also arise as inclusion neumatolítica (generated depth of the crust (Plutonism) by intrusion of magma, which causes alteration in petrographic composition of the invaded rock) then the crystals are included strongly on the rock, tourmaline is constituted by various mineral elements, but always has the same structure, the metals are always included in tourmaline and are causing varieties colors of this mineral.

MYTHOLOGY: The biggest fan of tourmaline was Tzu Hsi, empress dowager who ruled China from 1860 to 1908. The Empress used the stone as a notch in pins watch chains, or buttons jackets Imperial Court, tourmaline has both pyroelectric and piezoelectric properties. This means that at both ends opposite charges accumulate as much when heated under pressure. The tourmalines were introduced in Western and Central Europe in 1703 by the Dutch who imported it from Ceylon.

PROPERTIES: It is said that tourmaline multicolor helps to concentrate the mind, the soul, reason and body in a harmonious whole. From this "whole" wisdom and creativity are developed, stimulates fantasy and dreams, it helps to recognize the development.

The minerals stimulate compassion and the blue mineral promotes relaxation, sincerity and openness.
 

CHAKRAS:  All.

ZODIAC SIGN: Aries, Leo, Sagittarius.

USES: Jewellery, meditation, collection, for its piezoelectric properties have industrial applications such as the manufacture of pressure gauges, especially in submarine warfare equipment and instrumentation. This gem was used in the pressure sensor of the first atomic bomb. Brightly colored varieties were made in ancient times used to manufacture polarizers known as "tourmaline tongs".
