Description

One more finest group of pyrrhotite from Trepca! The pyrrhotite formed a nearly sphere-like group in the center of matrix, which is covered with tiny, sharp quartz crystals. The razor sharp terminated, highly lustrous sphalerite crystals help to give even more contrast to this well balanced, tri-dimensional and aesthetic group.
