Great larger specimen and although the photos do not do it justice because of the hghly reflective nature of the minerals, it is a terrific specimen. Under the scope you will see abundany deep red Pyrargyrite crystals with plates of silvery Polybasite. Comes with label of Arthur Kusche and US National Museum (Smithsonian), who acquire it from Carl Bosch. Good provenance (see provenance tab) with three older lables. Label matches number on specimen.
