2.2" Sphalerite, Quartz, Calcite & Chalcopyrite - Bulgaria

One side of this specimen displays a druze of sphalerite micro-crystals, as well as quartz crystals that protrude from the sphalerite beneath. The opposite side of this specimen contains a mix of calcite and quartz crystals, with chalcopyrite cubes grasping to the edge.
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.
