What is Cat’s Eye?
Cat’s Eye is a fascinating gemstone renowned for its unique optical phenomenon called chatoyancy. This effect creates a luminous band that moves across the surface of the stone, resembling the slit eye of a cat. The most well known variety of Cat’s Eye is chrysoberyl cat’s eye, though other gemstones like quartz, tourmaline, and apatite can also exhibit this effect. The chatoyancy is caused by the reflection of light off parallel inclusions or fibrous structures within the stone. With a hardness of 8.5 on the Mohs scale, chrysoberyl cat’s eye is highly durable and suitable for all types of jewelry.
