Gray Moonstone

A gem variety with constituents of orthoclase feldspar, known as potassium aluminum silicate.

It is a transparent to opaque oligoclase, a variety of plagioclase albite and sheet mica.

The optical effect of adularescence is a result of moonstone's unique structural pattern. Tiny inclusions of albite, a sodium aluminum silicate are intermixed with host rock layers of orthoclase, a potassium aluminum silicate.
