Moonstone is the most well-known gemstone variety of orthoclase feldspar, a potassium aluminum silicate. It is a transparent to opaque oligoclase, a variety of plagioclase albite and sheet mica. Moonstone is known to exhibit a distinct sheen under certain lighting conditions, and it is the sheen which renders moonstone one of the most remarkable gemstones.
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. As light enters the stone, it is refracted and scattered, producing an extremely unique and attractive play of both color and light. With moonstone, the aura of light actually appears to glow from deep within the surface of the stone.
