Tourmaline is found in two main geological occurrences. Igneous rocks, in particular granite and granite pegmatite, and in metamorphic rocks such as schist and marble. Schorl and lithium-rich tourmalines are usually found in granite and granite pegmatite. Magnesium-rich tourmalines, dravites, are generally restricted to schists and marble. Also, tourmaline is a durable mineral and can be found in minor amounts as grains in sandstone and conglomerate.
Today, gem and specimen tourmaline is mined chiefly in Brazil and Africa. Some placer material suitable for gem use comes from Sri Lanka. Some fine gem and specimen material has been produced in the United States, with the first discoveries having been made in 1822, in the state of Maine. California became a large producer of tourmaline in the early 1900s. The Maine deposits tend to produce crystals in raspberry pink-red as well as minty greens.
The industrial use of black tourmaline is based on the pyroelectricity, emission of far infrared radiation, adsorption of ions, release of negative air ions, and influence on biologic activity. The crystal structure of schorl was analyzed through a virtual three dimensional hard ball model and related to these properties. Explanations for the pyroelectricity, emission of far infrared radiation, adsorption of ions, and release of negative air ions are given based on the crystal structure characteristics.
Tourmalines are utilized in the manufacturing of hair care products such as dryers and hair straighteners. They come with negative ions and far infrared rays (FIR), which help improve the quality and appearance of your hair. They work great for frizzy hair. Styling tools that use tourmaline ensure smooth and shiny hair.
