Rainbow tourmaline, sometimes also called watermelon or Elbaite tourmaline, is a mix of tourmaline crystals that contain different kinds of inclusions. Inclusions of lithium, titanium, iron, or magnesium can result in red, green, blue, or yellow crystals, respectively. Watermelon tourmaline refers to green tourmaline wrapped around a red core, and can fetch a high price depending on the clarity.
