The aspect of this specimen that attracts me most is the fact that it is composed almost entirely out of Arsenopyrite. The specimen consists of a crust that is made up of scores of small orthorombic prismatic crystals with shallow dome terminations. They do not exceed 0.3" (8 cm) in length, and are in generally very good condition, with only about a dozen crystals showing damage or breakage. Their color is dark silver, and they have the standard metallic luster of most metal sulfides. The only other materials present are broken bits of quartz crystals and what appear to be some small patches of pyrite on the specimen's underside.
