A seldom-seen, classic and very fine cabinet combination plate from the historic mines at Trepca. Snow-white balls of tiny, glassy siderite crystals richly and aesthetically cover the sculptural specimen of brassy pyrite pyritohedrons, dark gray arsenopyrite crystals and a small forest of quartz crystals. Throw in a few, colorless, poker-chip calcite crystals and you have an outstanding combination piece from this famous locale. Ex. Franz Saller Collection.
