What is Cat's Eye Stone? The Enchanting Chatoyancy Effect

What is a cat's eye stone?

Cat's eye — also known as cat's eye gemstone or cymophane — is a semi-precious stone that owes its name to the remarkable chatoyancy effect: a narrow band of light that moves across the surface of the stone, resembling the eye of a cat. This unique visual feature is caused by fibrous inclusions or cavities in the stone that reflect light. Cat's eye is cut as a cabochon to best showcase the chatoyancy effect.
