Tourmaline [(Na, Ca)(Fe, Mg, Al, Li)3Al6(BO3)3 Si6)18(OH)4] is a highly variable mineral with a hardness of 7 to 7.5 on the Mohs scale. It occurs in many colors, including black, blue, green, pink, and colorless. The color is often zoned (more than one color in a crystal or gem). It is commonly associated with quartz and potassium feldspar, and is structurally related to beryl, cordierite, and dioptase. It is one of the few common Boron minerals. [Mineralogy, Perkins]
