This specimen is a half of a highly lustrous pyrite crystal that has galena and sphalerite crystals scattered on it. The one galena on the edge is an excellent spinel-law twin. The sphalerites are not sharp but, interestingly, have verytiny, I think, chalcopyrite crystals oriented on them. The oriented tiny chalco's, flash in the light when the specimen is turned. Interesting!
