    Kyanite is a polymorph of both andalusite and sillimanite. Polymorph gemstones share similar chemical compositions but they exhibit different crystal structures. Kyanite forms as triclinic crystals while andalusite and sillimanite are both orthorhombic. Kyanite most often occurs in various shades of blue.
