Pyrargyrite with Polybasite on Calcite (Ref: 16.1-471-(CN492))

Flower-like cluster of well crystalized Silver minerals perched on a sparkling white plate of Calcite. Esthetic composition with nice contrast as well. The largest crystals in the cluster are the Pyrargyrites which reach over 8MM and are the flat terminated habit. These are quite dark as almost all red color is gone, but with nice distinct form. The Polybasite crystals are more numerous but smaller, most showing the classic flat hexagonal habit. With a loupe there is some damage seen on the delicate thin edges of some Polybasites, Overall the main Silver specie cluster is excellent by naked eye and a few small balls of Calcite decorate the darker minerals nicely. Ex Charles M. Noll collection his label is included.
