This hand specimen consists of many heavily intergrown Cylindrite sprays. Each of these sprays is made up of dozens of tightly packed Cylindrite crystals, most of which are broken or damaged to some degree, that reach lengths of 1.3" (3.3 cm). These crystals have good form and the classic long, thin cylindrical shape whence comes their name. Their color is a moderately dark silvery-gray and their luster is metallic and rather dull. A small amount of a nondescript, dull-gray host rock is present.
