Likely the most intriguing aspect of this specimen is its form. The specimen consists of a cluster of very warped monoclinic Acanthite prisms that are heavily intergrown. Upon close examination, the cluster shows a curious blend of amorphous and crystalline tendencies, as if the largest crystal at the center of the cluster melted, and then started to crystallize in areas as smaller crystals, while most of the surface area "froze" in an amorphous state. Like other specimens that I have seen, this piece's base tapers down to a thin "stem". The visible crystals on the piece have relatively good form, with clean faces and edges that show off its metallic luster and dark gray color. There is a small spot of fresh breakage near its base where it was separated from its place of formation. Otherwise, there is no damage.
