Carletonite was identified in 1971 by G.Y. Chao, a geologist at Carleton University which is located in Quebec Canada; hence the name. Carletonite is a very rare crystal and has only been found in one location, Mt Saint-Hilaire in Quebec. This mineral has a property called pleochroism where it appears in different colors; blue, colorless, pink, or white; depending on the angle at which it is viewed. The crystals consist of alternating layers of silicate sheets and potassium, sodium, and calcium. It is mainly used as a mineral specimen and occasionally as a gem.
