The word tourmaline comes from the Sinhalese word "tourmali," meaning "mixed gemstones"
Tourmaline is a pyroelectric mineral, meaning that a voltage is created across the crystal when heated
There are 3
species of tourmaline: Dravite, Schorl, and Elbaite
Tourmaline
is a cyclosilicate, composed of rings of [(SiO4)]4-
tetrahedra.
Mineralogy:
Tourmaline is not a single mineral, but a group of several closely related
minerals. The most common of these minerals almost exclusively occur in granite
pegmatite. Tourmaline
is both Piezoelectric (electric potential difference created by pressure) and
Pyroelectric (electric potential difference created by temperature). If a specimen is put under either a pressure or temperature change,
it will generate voltage. When this happens, dust particles become attached to
the crystal ends.
Metaphysical: Heart Chakra crystal, self-healing,
compassionate vibration, masculine or yang energy
