Sphalerite – marmatite, sphalerite-cleophane, quartz,chalcopyrite , pyrite

An extraordinary, very aesthetic and extremely rare cabinet size specimen of black and opaque sphalerite-marmatite, developed on the top of quartz and chalcopyrite. In the last stage of the crystalizing of sphalerite, were developed several completely transparent green sphalerite – cleophane crystals. Chalcopyrite is corroded by pyrite is several places and lately oxidized to bornite, and as a result in some places could be seen very nice irization.
