Calaverite is closely related to sylvanite and differs only in silver content and slightly in hardness, cleavage, color and density. At times the two minerals are only distinguishable with chemical tests. Crystals of calaverite are unique and of interest to collectors. Typically found as striated prisms that can be twinned causing sharp bends, reticulated individuals and skeletal or arborescent formations. These clusters remind many collectors of writing.
Color is silver white to brassy yellow.
Luster is a bright metallic. Crystals are opaque. These are sometimes described as looking like writing. Also found as granular masses. Cleavage is absent.
