This small hand specimen consists of a cluster of hexagonal Pyrrhotite crystals that are partly intergrown. They make up most of the specimen's mass and do not exceed dimensions of 1.3 x 1.0 x 0.7" (3.3 x 2.5 x 1.8 cm). Though there is a small amount of visible damage, the crystals are generally in excellent condition and have a good hexagonal tabular form, with well-defined edges and clean faces that possess a dull, metallic luster. The crystals have a moderately dark reddish-brown coloration and, like most metallic sulfides, are opaque. Small crystals of at least 3 other sulfide minerals are partly embedded in the Pyrrhotites. One of these is pyrite, and the others appear to be sphalerite and galena. All show some vestiges of their respective forms, though their intergrowth makes them rather difficult to study in some areas. There is no host rock present on the piece.
