Moonstone is a trade name for any white feldspar with a blue “schiller,” a shimmery luminescence. Most often moonstone is the mineral microcline, although sometimes it can be orthoclase, albite, antiperthite or anorthoclase. The composition will be variable, most often KAlSi3O8, or (Ca,Na)[Al(Al,Si)Si2O8].

Moonstone is the traditional and mystical birthstone for the month of June, as well as the ayurvedic birthstone for the month of September.
