Color is lead to silver gray sometimes with a bluish tint.Luster is metallic to dull in weathered faces.Transparency crystals are opaque.Crystal System is isometric; 4/m bar 3 2/mCrystal Habits include the cube, octahedron and combinations of the two. Spinel twinning is possible forming flattened crystals.
