Fledspar Cats-eye is characterized by an enchanting play of light. It owes its name to the Blue Sheen which looks different when the stone is turned and is known as ‘adularescence’. – Caused by the lamellar inner construction of the gemstone. Incident light rays are refracted and scattered in the stone and a unique light effect is created.
Sri Lanka is the main source country of the Blue-sheen Fledspar – 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.
