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.
