A mineral of a steel-gray to black color and metallic luster, occurring crystallized, often in twin crystals shaped like cogwheels (wheel ore). The cog wheel shape is composed of four "twins" or crystals connected in a plane and forms a wheel with a jagged edge that resemble the teeth of a cog wheel. Majority of specimens show this pattern but not all. It is a sulphide of antimony, lead, and copper.
