Where did you find it? It looks like iron slag.

I'm sure one of the "rock guys" will chime in on this one.

Does a magnet stick to it?

any space peanuts??

space peanuts?

 

[lockdownking]

This could be several different things. But before I start guessing, are you sure that a magnet doesn't even slightly pull towards it? There are chemical tests that can be conducted also. Try dragging it on a piece of paper to see if it leaves a mark. Then post the mark on here.
Don't let NASA find out about it. ("snicker, snicker")
You said you found it on a beach, what state? Florida, Hawaii?

not sure if this is the smartest thing but i chipped off a piece of it and inside is very different.

is that silver? what is that crust? is it like a thin tar ish layer? how much does it weigh? can you post a close up of the inner and outer texture?

the pictures i have about the best quality i can get out of my camera. the outer layer is smooth (but it came from a beach) seems to be very thin. the inside is very reflective.

 

[arizonarock]

take it to a rock shop and have them look at it

It's kinda hard to tell from your pic's but I'm thinking some type of pyrite or zinc by the look of the fracture that you made in it? HH

thanks for the input. isn't pyrite flaky or brittle? this seems to be quite hard.

space peanuts?

never seen joe dirt...? lol

 

[hall]

haha yes now that you say joe dirt i remember the space peanut.

Either a non metallic meteorite or a hunk of hematite that is non magnetic. Both exist.

 

[searcher]

My first thought is hematite but you need to do a good streak test to be sure.

Do a streak test on the underside of your toilet tank lid. (easiest place to find non glazed ceramic)
If it streaks reddish or brownish --- hematite.
If it streaks grey/silver or blackish --- magnetite

If the rock effects a compass needle --- magnetite.

I'm not a rock guru but that is my two cents worth anyway...

Idk but thats really cool. Ive never seen anything like that.
