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 green tourmaline originates primarily in plutonitas acids, specifically pegmatite, where forms large crystals. Through the action of gases containing boron, from the magma on the host rock, the green tourmaline can also arise as neumatolítica inclusion (which is generated deep in Earth's crust (plutonic) intrusion of magma, causing impaired petrographic composition of the invaded rocks) then the crystals are included heavily on rock, green tourmaline is made up of different mineral elements, but always has the same structure, the metals are always included in tourmalines and are causing the colored varieties of this mineral, in this case the red nucleus due to traces of manganese as the green outside is iron, chromium or vanadium.

MYTHOLOGY: The green tourmaline is also known as verdelite "greenstone": all shades of green. The 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. 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.

PROPERTIES: It is said that green tourmaline transforms negative energy into positive energy and promotes patience, rejuvenates and inspires creativity, with green tourmaline we are able to see all possible solutions and select the most constructive. It is a mineral of prosperity and abundance, it helps to see the wonder of life. Green releases the feelings, increase the speed and responsiveness and arouse interest and enthusiasm. The green brings initiative and will to live, stimulates the sense and the ability of perception.
 

CHAKRAS: Heart.

ZODIAC SIGN: Taurus.

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".
