Description
Black tourmaline is the black variety of a group of crystals made up of sodium iron aluminum borosilicate hydroxide oxide. The presence of iron yields the crystal's black color.
History
The word tourmaline comes from the Sinhalese word, "turmeli," which means "mixed." A fitting name, as tourmalines come in such a variety of colors. Schorl, or black tourmaline, comes from an old German mining term. Black tourmaline was used as far back as the ancient Romans, who used the stone to promote restful sleep.
Healing Properties
In chakra healing layouts, black tourmaline is placed between the feet to ground the person as it balances the chakras. It is also used to alleviate arthritis, heart disease and sore throat.
Metaphysical Properties
Black tourmaline absorbs negative energy and is a useful stone for this purpose. When carried on your person, black tourmaline is said to alleviate stress caused by insecurity or anxiety. It can also be used to increase psychic talents.
At Home or Work
Because black tourmaline is a piezoelectric stone, when it's rubbed or heated, it will give off an electrical charge at both ends--one positive, the other negative. Therefore, black tourmaline is invaluable around computers and other electronics, as it will absorb the negative energy from electromagnetic fields.
