Caused by the lamellar inner construction of the gemstone. Incident light rays are refracted and scattered in the stone and a an unique light effect is created. Sri Lanka is the main source country of the Blue-sheen moonstone - the most attractive type. Some Moonstones display a single ray like a chatoyant effect and are called Cats-eyes which are rare and much sought after by Collectors.
