For sale is a very nice chalcopyrite over tetrahedrite all sitting on quartz crystals, from Madan ore field, Bulgaria. The chalcopyrite thinly coats the tetrahedrite, and in some areas it has come away, showing the brightish tetrahedrite crystal. There a few tetrahedrite crystal that have no chalcopyrite associated. The rear of the piece show some bright pyrite and also some yellow translucent sphalerite, and a bit of galena in there as well.The placement of the crystal in the center of the wonderful transparent quartz crystals is very good. All crystals are in pristine condition. I am particularly fond of this specimen, the crisp sharp metal crystal are just pretty.
