Looks like pyrite. Should strike sparks from a file or other hardened steel.

I agree. Looks like Fools Gold.

before I scrolled down, pyrite was my first thought, mainly because its about the only rock I know :laughing9: :icon_thumright:

I'm going to go against the grain and state chalcopyrite instead of pyrite. Both have similar composition. Pyrite (fool's gold) is mostly crystaline structure, often cubic, even massive. Chalcopyrite has enough copper in it to look slightly duller with smaller crystaline structure (at least in my area).

One way to tell the difference will be a streak-plate test: scratch the stone on an unglazed tile surface, and take a look at the color left. Most of the pyrites will leave a colorful streak (look 'em up online). An iron-nickel meteorite will leave a different color streak, if at all. Most are so hard to leave little streak: like trying to get a streak from a stainless steel fork, spoon or knife.

Good call... it does have a very fine structure, not blocky. You can use the bottom rim of a coffee cup to scratch test. Also a good knife sharpener. ;D

Not a meteorite, Streak test will show gray im guessing (Fe02). Cool rock though!!!!!

It is all silver looking, not gold.
Then something is odd about the lighting of the photos. Were they taken under fluorescent lighting? If so, the color shown is not the true color. Need to add photos of the stone taken in natural light.

Chalcopyrite should be more copper-colored, not gold. But silver coloring suggests something closer to galena (lead sulfide).

Try doing a Google search for images of chalcopyrite and galena, and tell us which one seems closer.

Hmmmmmm, why does this look familiar? :icon_scratch:
I'm guessing it is slag. I had a very similar find some time ago, and yours looks a lot alike:

May be in the schist family

Schistosity does not make it schist, if you follow me... :laughing7:

If it is schist, it is super-mica-schist.

Hope nobody minds me talkin' schist on the forum. :wink:

That whole area could be full of schist!

For a test, would a magnet draw to a meteorite?

After seeing the show "Meteorite Men" I would say YES a magnet should draw to it.

It is true that the great majority of meteorites are magnet susceptible, however, there are many types of meteorites that do not show much magnetic attraction. These types are often more valuable than the typical Iron/Nickel meteorites that are attracted to magnets strongly. They are often harder to find as they will blend in with terrestrial rocks easily.
