An excellent miniature of very well-developed tetrahedral Sphalerite crystals all to about 1 cm along each axis and forming a domed hedgehog-like structure. From the Madan Ore Field in the Rhodope Mountains of Bulgaria, a deposit famous for its very fine metal sulphides. The crystal faces are lustrous with a silky sheen and speckled with sub-mm brassy-golden Chalcopyrite crystals.
