The old hand-written label claims that there is Gold in this specimen. I really don't agree with that unless it is super small. It is cut and polished on one side, which may have brought out the allusion of Gold. I think it is just Pyrite as it is brittle and much harder than Gold. The rest of the specimen is indeed composed of dark black and sectile Petzite.
