Achroite is a rare and colourless variety of tourmaline. It was first described in 1914 by mineralogist Waldemar T. Schaller. Its name is derived from the Greek word “akros,” which means “topmost.” and named so because of its colourless to white appearance, which is considered the lightest colour in the tourmaline group.
Achroite is seen in many parts of the world which include Brazil, Madagascar, Afghanistan, Pakistan, Russia, and the United States. Achroite usually occurs in pegmatites and metamorphic rocks.
