Black Tourmaline

Tourmaline is found in all the colors of the rainbow, and also in combinations of two or three colors.  Most people consider tourmaline to be a single mineral, but in fact it is a name given to a group of closely related minerals.  There are many interesting and unique properties of tourmalines.  They are piezoelectric, meaning that when a crystal is heated or vibrated, a different electrical charge will form at opposite ends of the crystal.  Conversely, if an electrical potential is applied to the crystal, it will vibrate.  Also, tourmalines are pleochroic, meaning the crystal will look darker in color when viewed down the long axis of the crystal than when viewed from the side.  The name "Schorl" is given to the black variety of tourmaline, which is Sodium Iron Aluminum Boro-silicate Hydroxide.  This is the most common variety of tourmaline.  Tourmaline crystals are interesting because they are hemimorphic, having a different shaped top from the bottom of the crystal.  Black tourmaline is a powerful stone for repelling negativity.  It also provides protection from radiation, electromagnetic smog, and magickal spells.  Use black tourmaline to enhance emotional stability, and stimulate practical creativity.  It enhances physical vitality and awareness, and lessens fear and obsessions.

Physically, black tourmaline is beneficial to the lower back, arthritis sufferers, adrenals, immune system, and those with gout.  It can help with dyslexia, heart disease, anxiety, and disorientation.

Black tourmaline is associated with the root chakra.  It is a powerful stone for opening this energy center.
