Scratch test it on the back of a toilet lid or under a porcelain sink if it leaves a mark its Hemitite or magnetite, no mark then grind a flat spot and look for dots or nickle pattern. It won't ruin the value. Looks like a meteorite. Best looking one I have seen so far anyways. This one I found passed all the test but it's still a meteorwrong I'm sure. The inside was interesting with crystal matrix and rusted a week after I split it. Before it was solid black in the inside with dots of lighter and other color. No fusion crust on it. Weight is about 15 pounds for its size thru me off, magnet sticks and so on. But I still don't give it the pass.
