Trepča Stan Terg Mine (Stari Trg Mine; Trepča Mine), Trepča complex, Trepča valley, Kosovska Mitrovica, Kosovo
The minerals list for this one reads like a phone book! It's got a little bit of everything, and the overall aesthetics are spectacular! The thin blades you see are the Pyrrhotite, and the black crystals scattered around are the Sphalerite. The pale, pink balls on the right side are the Rhodochrosite, and on the back side is some grey Boulangerite. On the bottom-front are quartz crystals. Some of the pyrrhotite blades, especially at the bottom, have an iridescent sheen to them. A really, really impressive specimen!
