Moonstone is a typical Potassium Aluminum Silicate with several commonalities with the Feldspar family.  It’s name is derived from the visual effect or sheen that is caused by light reflecting internally and externally from the layer inclusions of different Feldspars.  Moonstone is closely related to Sunstone, Labradorite and Sodalite.
