Black Tourmaline is also called Schorl, and accounts for ninety-five percent of all Tourmaline in nature. It is black, or sometimes a deep blue that appears black. The term Schorl was in use before the 1400s, named for a town in Saxony, Germany, where Black Tourmaline was found in nearby tin mines. Black Tourmaline belongs to a complex family of aluminum borosilicate mixed with iron, magnesium, or other metals that, depending on the proportions of its components, may form as red, pink, yellow, brown, black, green, blue or violet. Its prismatic, vertically striated crystals may be long and slender, or thick and columnar, and are uniquely triangular in cross-section. The chemical formula for Black Tourmaline is NaFe2+3Al6(Si6O18)(BO3)3(OH)3(OH).
Black Tourmaline is known as a good grounding stone and useful for people who are facing large amounts of stress at work or home, and it is a good shield to protect from environmental pollutants, electromagnetic smog, and radiation in everyday life. When worn it also aids in the protection from energy drainers.
