Moonstone is the most well known variety of orthoclase feldspar. It characteristically exhibits a milky floating blue light known as adularescence or the schiller effect. This lovely sheen is due to a combination of orthoclase and albite arranged in layers. Light reflected from the layers if they are not too thick is responsible for the unusual optical properties.
