Cat’s-eye, any of several gemstones that, when cut en cabochon (in convex form, highly polished), display a luminous band reminiscent of the eye of a cat; this particular quality is termed chatoyancy. Precious cat’s-eye, the rarest and most highly prized, is a greenish chatoyant variety of chrysoberyl called cymophane.
