Moonstone color

Moonstone or "Adularia," an orthoclase feldspar, was initially named for an early mining site at Mt. Adular in Switzerland. From this tradition, we derive the term "adularescence," which is the optical phenomenon of iridescence, which creates a billowy, floating blue to white light in this gem.
