Description
This is a super combination piece with slightly deformed, tetrahedral crystals of Chalcopyrite, scattered over relatively large Sphalerite crystals. Both species are well developed, sharp and lustrous and they are showing a clear striation as well. There are also numerous of glistening, golden crystals of Pyrite perched on the Chalcopyrite. Definitely a top specimen without any imperfection.
