Pyrite.  Venezuela.

Pyrite. Venezuela.

Pyrite, FeS2, Iron sulphide.  There is not a lot to say about this familiar mineral, except that it is a mineral that is found in nearly all geologic environments. I don't like collecting minerals unless I know exactly where they came from, however this is such a nice specimen that i just could not resist it's purchase. The only information that I have is that it is from Venezuela.
