About Cat’s Eye (Lehsunia)
Cat’s Eye is best known for its remarkable optical effect called chatoyancy, where a bright band of reflected light moves across the surface of the gemstone, closely resembling the eye of a cat. This rare phenomenon is caused by fine parallel needle-like inclusions within the gemstone.
The finest Cat’s Eye gemstones belong to the chrysoberyl mineral family and are highly valued for their sharp, well-defined eye effect, durability, and rarity. Throughout history, Cat’s Eye has been regarded as a gemstone of protection and good fortune.
