description Kornerupine Cat's Eye Overview
Kornerupine cat's eye is a chatoyant variety of kornerupine, a rare magnesium-rich boro-silicate mineral. Its narrow band of reflected light is produced by parallel inclusions or internal structures that align within the cut stone. Kornerupine itself is usually green, brown, or yellowish, while cat's-eye material is valued by collectors for the clarity and movement of its optical effect. Important gem material has been reported from Greenland, Sri Lanka, and Madagascar.
