Its hardness is 6, and its specific gravity is 3.122. This mineral would make an opaque gem or an ornamental stone, as the color, though lighter, is often as rich as that of lapis lazuli, for which it was mistaken when first found.
Cassiterite has not been observed in fine crystals, what has been found being clear enough to cut only small transparent gems.
