This small thumbnail piece consists of a cluster of many tiny Pyrargyrites. These crystals do not exceed 0.3 x 0.2 x 0.2" (8 x 5 x 4 mm) but are generally in very good condition, showing no fresh damage. Their hexagonal prismatic form is very good, and all show a dark gray color and bright, nearly metallic luster that is caused by an oxidation coating and is common for this mineral. This coating also renders them essentially opaque in normal light. There is a very small amount of a white host rock present.
