smooth weird rock

You've got a nice piece of magnetite there. Where'd you find it? To be sure see if you can pick it up with a magnet.
 
I suspect that you might have a nickel/iron meteorite fragment. It would rust like that and can be
attracted to a magnet. If it's magnetic by itself, then I suspect you could have something else or it
could have been magnetized by prolonged contact with a magnet, which still asks the question,
"What is it?"

The Barringer Crater is in the southwest, U.S. Many fragments having similar appearance,
have been found in Diablo Canyon near Winslow, Arizona. I have a fragment from that area, which
I used in my classroom for years. You can purchase fragments, but I suspect that you no longer
need to purchase one. You can easily look on the internet and compare your sample with fragments
being offered for sale by reputable dealers. There is also a meteorite collectors' convention each year
in the southwest.

Meteorite fragments are found in many places on the earth. Yours, if it is, may have landed where you
found it or was carried by a person and lost where you found it. Because many different craters have
produced fragments with slightly different appearances, some experts are sophisticated enough to be
able to tell, with some degree of accuracy the possible crater source.

I won't bet my classroom reputation on this hypothesis, but I feel secure enough to suggest that you
may have a nickel/iron meteorite fragment.

Ok so I tested it with a magnet and it didnt stick
It feels like a rock though

Any idea's
 
Well, at this point in the research, you've successfully eliminated a nickel/iron meteorite.

Obsidian could make some sense. I believe that obsidian is a volcanic glass type rock from which the
Native Americans made arrowheads and other sharp tools. It chips like flint, but is more glass like.

At this point, your item is still an, "I don't know."

There is an extremely remote possibility that your item is a crystalline meteorite, but the only ones I've
ever seen were more greenish like peridot. There may well be other crystalline meteorite substances
with which I'm not familiar.

I'm terribly sorry that I couldn't have been of more help.

Where found?

Maybe a piece of volcanic splatter?

HH,
I concur.... but interesting rock
 
I love thewhatzit rocks. My guess, it looks like weathered schist with an iron patina. These are sedimentary rocks which where subject to slight metamorphic composition (pressure and heat). The original sedimentary rock should be a fine grained sandstone or siltstone. Check for any distinguishable grains with a 10x magnifying loupe or glass (the grains could be jointed or compressed/flattened). The grains are aligned and are shiny/reflect sunlight under certain angles. ALso, sedimentary rocks and schists are relatively light in weight. Ore, including meteorites are generally heavier. The best way to check is to split it and examine the fresh face but you would ruin it when it turns out to be a non magnetic meteorite.
