Watch a video of this specimen by following the Vimeo link below: https://vimeo.com/940326139 Here is a quite unusual specimen from Trepca displaying very lustrous sharp and twinned sphalerite crystals (sometimes coated in a thin layer of iridescent oxides) scattered over two balls of galena that epitaxially overgrow two pyrite pseudomorphs after pyrrhotite. This contrasting metallic combination is completed with a rosette of dolomite-rhodochrosite, clear quartz sprays, a brassy chalcopyrite and small boulangerite hairs here and there. A carefully selected specimen from the recent discoveries in Trepca. Discovery horizon 10 (-685m) south in 2021.
