Tourmaline was first discovered in Sri Lanka. It was first brought to Europe by the Dutch East India Company. The most common tourmaline is schorl, it makes up about 95% of all tourmaline. Tourmaline comes in just about any color depending on trace elements found in the semi-precious gem. Multicolored crystals are common and this is one of the desired properties of the gem. The color of tourmaline can also be altered by heat and radiation. Tourmalines can now be found in Brazil, Tanzania, Kenya, Madagascar and primarily in Maine and California in the United States. Tourmalines are a great addition to a fashion ring, pendant or earring.
