| Description | Anorthoclase, KAlSi3O8 (potasium aluminum silicate), is a polymorph of other minerals that share the same chemistry, but have different crystal structures. Anorthoclase usually has a flattened crystal habit. Moonstone comes in colorless, white, yellow, orange, and gray. It always has a white or blue sheen. That is, moonstone reflects light in a distinctive shimmering phenomenon known as adularescence. |
