We could use your honest opinion on this object. A friend suggested meteorite, even though there wasn't much fusion crust left on it. We did some research online an the closest resemblance was the hexahedrite with the blue fusion crust. We also did some home tests; this is what we know:
The dull grey/blue exterior was grazed with a small grinding wheel. It now looks like shiny new metal with only a few spots that show rust after getting it wet. Has weak magnetic attraction, leaves light grey streaks on non-glazed porcelain, heavier than other rocks of it's size, looks like chrome inside when sawed, but has micro bubbles when chipped off. After chipping off a small piece, we hit with a hammer. It crushed like stone with some very shiny specks that flattened out, and the rest turned to powder. All particles were picked up by a magnet.
We have looked at thousands of pictures of meteorites and meteor-wrongs, foundry slag & ore, and we only found three that were close. All of which were confirmed meteorites. Unfortunately, origin and history are unknown. What do you think? If not meteorite, do you have a clue of what it might be? Thank you for your time.

Hey guys, thanks so much for your feed back and support! We still have no idea what it is yet, but
we have done more tests in the last year. Ps- Sorry, I had forgotten my log in information there for a while.
Anyway, here is what we know:

After nearly two years of research, and having it tested at a state university, we were able to discover some minerals
that it contained, but are still not 100% positive of what the item actually is. The test results show:
Cr/F/Fe/Mn/C/Si/Co as well as several small spikes that were unidentified. Under a microscope, it shows red, yellow,
green, white, and clear crystalline. There was also some rust with a week attraction to magnet. The item is not man made,
that much we were able to figure out.
