A large spray of Cylindrite spikes permeates the gray metallic host rock of this cabinet specimen. It is likely that many of these crystals exceed 2" (5 cm) in length, and though many of the exposed crystals are damaged or incomplete, those that extend into the host are in good condition. The crystals have the classic cylindrical shape that is the hallmark and namesake of the specie, and all have a dark silvery-gray color and a dull metallic luster- each strongly resembles the lead of a pencil. I cannot define the host rock, but it appears to contain a substantial amount of calcite.
