Mineral Description
 
healing crystals
Black tourmaline that has been tumbled and polished. These are not the small 1/2 inch to 1 inch tumbled stones everyone else sells. These are large and beautiful 1 1/2 to 2 inch stones. Only the very best at Kidz Rocks!

You will receive one specimen that is 1 1/2 inch to 2 inch and weighing 2 ounces. Please see the group photo before purchase as this item varies quite a bit in shape from one piece to another.

Bulk Purchase Specimen
You are buying one rock. You will receive a rock like the ones in the photographs, not the exact rock shown. The photograph with multiple rocks is so you can see the range of differences in this bulk purchase specimen listing. Photographing and listing every rock separately adds a lot in labor costs. We pass that savings on to you with lower prices and higher quality than the competition.


Black Tourmaline, or Schorl , is a crystal boron silicate mineral compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gem comes in a wide variety of colors. The name comes from the Sinhalese word Thuramali meaning stone attracting ash (a reference to its pyroelectric properties) Black Tourmaline is the most common species of tourmaline.

Tourmaline is distinguished by its three-sided prisms; no other common mineral has three sides. Schorl and lithium-rich tourmalines are usually found in granite and granite pegmatite. Gem and specimen tourmaline is mined chiefly in Brazil, Africa and California. Tourmalines are favorites among mineral collectors. Black tourmalines can shine nicely and produce sharp crystal forms. Tourmalines are piezoelectric which means that when a crystal is heated or compressed (or vibrated) a different electrical charge will form at opposite ends of the crystal (an electrical potential).

Black tourmaline gemstone jewelry was very popular during the Victorian era in mourning. Native Americans have used pink and green tourmaline as funeral gifts for centuries. Brightly colored Sri Lankan gem tourmalines were brought to Europe in great quantities by the Dutch East India Company to satisfy a demand for curiosities and gems. At the time it was not realized that schorl and tourmaline were the same mineral.

HEALING PROPERTIES

Black Tourmaline is a powerful stone, with a long history among many cultures of providing protection during ritual work. It can be used for scrying, and was traditionally used to point out a cause of trouble or an offender, and to indicate a good direction in which to move. This article explores not only Black Tourmaline and it's use as a psychic shield, an electric stone, a luck talisman and more; but the second half of the article explores how it works in combination with quartz.

Black Tourmaline is best known as a grounding and protection stone.

It has the following associations: Element: Earth, Chakra: Root, Deity: Manat, the Arabian Goddess of Waning Moon, Time, Destiny and Death. Astrological: Capricorn and Libra Today Black Tourmaline is still revered as a premier talisman of protection. Think of it as a psychic shield deflecting and dispelling negative energies, entities, or destructive forces. Or you might think of it as a lightening rod, taking any negative energy and grounding it into Mama earth where she can transform it back into pure potential. It promotes a sense of power and self-confidence, allowing for a clearer, more objective view of the world. Black tourmaline is empowering to those who must live or work in challenging environments or when facing difficult circumstances.

Mystical Tradition says to rub black tourmaline for luck and happiness. This reputation as a powerful stone and a very lucky stone, might come from the piezoelectric qualities. When the tourmaline is rubbed it becomes charged with magnetic electricity and the luck intensifies.
