Plagionite is an uncommon lead, antimony sulfosalt and this rich, old-time specimen is from the famous Type Locality - the Graf Jost-Christian Mine, Harz Mts., Germany. This ancient antimony mine was opened around 1700. The lustrous, striated, tabular, metallic-gray Plagionite is present as flat-lying crystals that range from 1-3 mm. They are beautifully visible in a rich seam on contrasting matrix. Acquired in 1978 by Fioravanti in an exchange with the museum and accompanied by labels from the Mineral Museum of the University of Napoli.
