Scores of Cylindrite crystals are partly intergrown to form this hand specimen. The crystals are in fair condition at best, as most of them are broken and incomplete, and do not tend to exceed 1" (2.5 cm) in length. All have the tapering, cylindrical form that is classic for this mineral, along with the standard dark gray color and dull metallic luster. There does not appear to be any other material present.
