3.1" Sharp Calcite Crystals and Pyrite on Quartz - Mitrovica, Kosovo

This is a beautiful, 3.1" wide cluster of quartz crystals that are covered in sharp calcite crystals and pyrite. This material comes out of the Trepča mining complex in the Mitrovica District, Kosovo (likely the Trepča Stan Terg (mine)).

The Trepča Stari Trg mine is the largest lead-zinc-silver mine in Europe and produces many fine mineral associations such as this one. Located in the Trepča complex, Trepča valley of the Mitrovica District, Kosovo. The mine's ore veins are hosted in Upper Triassic limestone that has been subjected to the recrystallization process. Minerals from this mine are quite stunning and were formed via two stages of open-system and closed-system mineralization. The open-system stage formed a breccia and was injected with a high amount of outside mineral seepage. This process is responsible for most of the more attractive minerals to come out of the mine. These minerals include: vivianite, pyrite, galena, sphalerite, hedenbergite, manganoan calcite, marcasite, arsenopyrite, and quartz.

Records of the mine's activity extend into the middle ages and has been a large part of Kosovo's involvement in the mineral market to this day. The mine was temporarily shut down during the Kosovo war in the late 1980's, where equipment was destroyed and the mine was heavily flooded. Until the early 2000's the mine was inactive and the outflow of minerals ceased. Specimens from this mine are currently on the rarer side, though they should come back in full swing soon.
