Tourmalines were first discovered in the late 1600s or early 1700s by Dutch traders operating along the west coast of Italy but now are found in many parts of the world including California and Maine. The name tourmaline is from the Sri Lankan language meaning all coloured crystals and because ancient gemologists and dealers couldn’t differentiate one stone from the other all were classified as tourmalines, hence the error of identification of Pink and Red Tourmaline even though the Pink Tourmaline is pinker than a ruby.

Tourmalines are formed by hydrothermal activity, a process that carries hot water and vapours along with the necessary elements to form crystals in pockets, cavities, fractures, fissures, or any open space in igneous and/or metaphoric rock where crystal growth can occur. This hydrothermal activity is also responsible for the formation of emerald, fluorite, amethyst, and rock crystals.
