hexagonaria: For me, it was really process of elimination, it looked like an igneous rock and none of the other ones seemed to fit and rhyolite is one that always seems to look different to me, so that's the one that I picked. It is quite a strange sample though... >.>

I've learned from experience that getting a JPG/Wikimedia pic works best.
If still no one can see it, someone else can post a question

Bornite?
I can't tell if it has metallic luster or not.

Chalcopyrite? I know conventional chalcopyrite looks much more like...well, pyrite, but i think it gets this kind of bornitesque look when it tarnishes.
