An old German pyromorphite from the Rosenberg Mine.  There are crystals all around the specimen, though one side is slightly more concave so the crystals have been better preserved (many on the opposite side are sheared) This mine operated between 1763 and 1963, and is responsible for producing some of Germany’s best pyromorphites.  When I first started collecting, before the now prolific Chinese finds, your options for a good pyromorphite were basically one from Les Farges, one from Spain, one from Bunker Hill, or you could save up for one of these—even back then they were considered classics and somewhat harder to find!
