The manganese oxide base of this piece is partly covered with a thin crust of Turgite, a variety of Hematite. This crust shows no crystal form and is extremely thin, but is easy to see due to its varied coloration, which span the visible spectrum. Resting atop the crust are two incomplete cyclic twins of cerussite that are in good condition and show reasonably good crystal form.
