19TVR14: Galena, Quartz, Rhodochrosite, Calcite

Isolated crystals of Galena with pentadodecahedral forms modified by cube faces, and showing dissolution and corrosion figures on some faces and polycrystalline growths on others, on a matrix covered by slightly pink carbonates formed by intergrowths of Rhodochrosite and Calcite. Finally, the combination is adorned with a good number of water-clear Quartz crystals, some of them aerial. The Trepča mining complex is one of the largest polymetallic deposits in the world and for many years produced exceptional pieces, and still now, of Sphalerite as well as various combinations of sulphides and carbonates, as displayed in this specimen from the former collections of Ferat Voca.
