Cat's Eye

Cat's Eye is a mineral gemstone variety of quartz characterized by a unique optical effect called chatoyancy, where a luminous band moves across its surface as you change the viewing angle. This effect resembles a cat’s eye and is caused by needle-like inclusions or fibers within the stone that reflect light. Typically found in shades of yellow, green, or gray, Cat's Eye is valued for its striking appearance and is often used in jewelry. Its distinctive glow requires careful cutting and polishing to enhance the chatoyancy, making it both a beautiful and intriguing gemstone.
