Pyrite?

A very nice specimen of it by the picture.

That part that is in focus is pyrite - little doubt. It can help to take the photo from farther away, then enlarge the part of interest...

Pyrite for sure. But don't reject it outright - gold can be found with pyrite. Check it carefully for gold included in it.
