This small hand specimen consists of several small Acanthite clusters and formations that rest on a gray limestone base. These formations are mostly massive in habit, but a few tiny crystals are visible, along with some semicrystalline formations. The crystals have excellent pseudocubic form, and one area shows some thin, prismatic forms. The mineral shows the standard dark silvery-gray color and a dull metallic luster.
