This small specimen consists almost entirely of native Arsenic by weight. It is almost purely massive, though there are a few areas that show some tiny reniform formations that show a dull metallic luster- the massive material has a duller luster that is almost matte. All of the Arsenic has a dark gray-black coloration. There is a very thin, uneven crust of a pale brown, chalky host rock coating one area.
