The structure is rhombohedral and consists of a stack of several puckered layers of bismuth atoms: the atoms are positioned above and below the mean plane of each layer.
In its highly pure form, bismuth can develop iridescent crystals—exhibiting yellow, blue, pinkish-purple, and dark green hues—which are commonly sold as collector's items.
Lead-free bismuth compounds are used in the cosmetics industry and in medical applications.
