The famous Trepca Mining District, a world-class locality for numerous sulfide and gangue minerals, has recently started producing fine specimens again. This is a choice large group of well-formed hexagonal pyrite crystal psuedomorphs after pyrrhotite, covered on top with a preferential overgrown of calcite and quartz giving a very aesthetic “snow on the mountain” effect. The pyrite after pyrrhotite psuedomorphs from Trepca are the best in the world and this is an excellent and quite large example. A classic association for Trepca, and in nice condition considering the large size of this showy piece. Mark Cross photo.
