Opal cat’s eye is a rare variety of opal that exhibits a unique optical effect known as chatoyancy. This effect appears as a narrow band of light across the surface of the gemstone, resembling the eye of a cat.
This phenomenon is caused by the internal structure of the stone, where light reflects in a concentrated line. The result is a distinctive and dynamic appearance that changes with movement and lighting.
The cat’s eye effect is best seen in well-cut cabochons, where the curved surface enhances the reflective band. Stones with sharp and centered lines are considered more desirable.
