Kyanite has been used as a semiprecious gemstone, which may display cat’s eye chatoyancy, though this use is limited by its anisotropism and perfect cleavage. Color varieties include recently discovered orange kyanite from Tanzania. The orange color is due to inclusion of small amounts of manganese (Mn3+) in the structure.
