2.1" Sphalerite Crystal Cluster - Bulgaria

This is a cluster of opaque sphalerite from the Borieva mine, located in the Rhodope Mountains of Bulgaria. A quartz crystal can be found along the edge of this specimen as well.

There is slight repair and stabilization to the underside of this specimen.

The Madan ore fields are located in the Rhodope Mountains of Bulgaria. This long stretch of mountain range in Southeastern Europe is home to a variety of incredible minerals, with sulfides being some of which show great variety in these mountains. One of these sulfides is gold ore, a mineral that is mined consistently from the Rhodopes, though is typically found containing relatively high amounts of cyanide. Because of this, there is an additional cyanide extraction process that takes place before the gold can be applicable for whatever use.
Other sulfides like galena, sphalerite, and chalcopyrite of all shapes and sizes, can be found throughout this mountain range.
