Moderately lustrous silvery-gray Stromeyerite can be seen in / on this extremely rich ore specimen from the Zmeinogorsk Mine. This old massive volcanogenic sulfide deposit was developed from 1745-1871 and examples of any species are rare from here. A historic and rich miniature, accompanied by a label from the legendary mineral dealer, Hugh A. Ford. Since the label has Ford's New York address, it dates to 1946-1957.
