Gold colored pyramid shaped nuggets in granite. Conducts electricity.?

I've got this chunk of granite like rock that has a whole bunch of hard, heavy, nugget things embeded in the rock.

They are gold and silver colored double sided pyramid shaped things that conduct electricity and I have no idea what they are, or if they're valuable.

ANY ideas what they are?

    Most likely they are iron pyrite or fool's gold. One of the crystal shapes they can take is an octahedron, which looks like a pyramid if you only see one side of it sticking out of the granite. If there are a lot of them in this peiec of granite and they are well shaped, some rock collectors might give you a nice sum of money for the rock.
