The name moonstone derives from the stone's characteristic visual effect, which produces a milky, bluish interior light. This effect is caused by light diffraction through alternating layers of orthoclase and albite within the stone. The diffracted light varies from white to blue, depending on the thinness of the albite layers. Polished moonstones often display a "cat's eye" effect, a luminous streak through the stone. Asterism is rare and produces four-pointed stars.
