Moonstone is a variety of orthoclase feldspar, which is a sodium aluminum silicate. Moonstones can occur colorless, blue-white, white and pale shades of apricot and peach. The rarest and most expensive moonstones will be colorless with a floating blue color or schiller that seems to hover above the stone. This phenomenon is termed adularescence and is due to a combination of orthoclase and albite feldspars, arranged in layers. Light reflected from these layers produces interference effects and causes the adularescence. If the layers are very thin, a blue schiller is seen; when they are thicker a white schiller is seen.
The most important source for moonstone is Sri Lanka. Water-worn stones are often found in the alluvial gem gravels on the southern part of the Island.
