Zeunerite (rare Locale)

Item Description

Zeunerite is an uncommon hydrated Cu-U arsenate. Green lathes and crusts richly cover the front with thin films noted on the back of the sandstone matrix. Tyrolite may also be present. This extinct mine dates back to the Roman era! Self-collected by a collector named Paco Gutierrez, and came in his collection - the only such we have seen.
