Sharp siegenite crystals on brassy chalcopyrites that have formed an epimorph or cast after galena cubes. A nice calcite prism sits at the front and there are also gemmy dolomites on the chalcopyrites.

Brilliant dark sphalerite crystals with flashes of orange host calcite crystals on some of the faces, at the top and most of the rear of the specimen. Unfortunately the label just says Hardin County, Illinois. Acq in 1990.
