Calcite on Arsenopyrite and Sphalerite, Trepca Complex, near Mitrovica, Kosovska Municipality, Kosovo Miniature 4.5 x 6.5 x 7.5 cm $450. Online 8/18
Mounded group of sphalerite richly covered with very high sheen arsenopyrite and a few calcite crystals scattered over the surface. This is probably the best arsenopyrite I acquired in the batch...there were a couple others equally as nice but smaller miniatures. Mined 2014 and in great condition. Really a good piece.
