Is this an authentic meteorite?

[Spartcom5]

I bought this earlier for $10 and the guy claimed it was a Campo Del Cielo meteorite. I normally don't buy things like this but I liked it. He offered if it was fake that I could get my money back. To me it looks pretty good? It is magnetic as well. I will bring it to my friend to have the composition electronically tested.

Hate to burst one's bubble but to me looks like some type of slag..for 10 bucks and a piece that attracted you, you are really not out but have an addition to your collection..

It has no visible characteristics of meteorites. Magnetic attraction is an indicator only when combined with other factors. If you want to learn more about meteorites, pick up a few guidebooks.

Time for more coffee.

I don't see it resembling slag at all. Slag almost always has gas holes. It looks like it might have had a fusion crust that has possibility been removed. Don't know. I think it's worth investigating.
Specific gravity test is a good place to start. Streak test, hardness should indicate iron and a nickel test can be helpful.

It looks just like the Campo Del Cielo meteorite that I have and what you [TABLE="class: infobox, width: 280"]

see on the internet. So unless mine is fake I'd say it's good. I guess try posting it in the meteorite forum?

I have a genuine one also and it looks almost identical. It has been cleaned and this is what they look like cleaned.

I will have to look closer at this. I have not seen this before. Time to download a few dozen high quality images and call around to see if someone nearby has one. Never to late to learn.

Also, it still looks quite a bit like small bits of steel that have been through a fire, but did not fully melt. That is what one of the local blacksmiths passed on to me. Hence, my original skepticism.

Time for more coffee.
