Amazing.

I'm not sure what this is, but I found it on the beach a while ago, in New England.
Much heavier than any other rock of the same size. I have a feeling it's a meteorite, but I've never gotten it checked. It also has a weird indentation on it, like a profile view of somebodies thumb.
Any ideas?

Geologist here.

It could be a meteorite, I'd definitely get it checked. Is it magnetic?

other possibilities are industrial slag or perhaps a manganese oxide nodule of some sort. But it does look similar enough to some meteorites that I'd definitely get it looked at.

something that size would be worth hundreds or perhaps thousands of dollars if it's a meteorite.

It's slightly magnetic with common refrigerator magnets. They won't stick, but you can feel it pull.
I'm pretty sure I have a piece of slag too. Got kind of excited again until it dried off and you could really tell.
Slag to the left, and only weighs half as much.
Not sure I've seen the oxide before, but in pics I can see some similarities.
Wow, that's impressive. I'm not sure if I'd sell it though. I've had it for so long. It's become quite important.
I mean, a few thousand... I'd have to think really hard about that.

Are these natural stones or man made? I read that opalite is a man made glass and I'm confused.
>>
>>2915867
They're glass.
>>
>>2915867
Opalites are a man-made glass. There do exist natural Opalites, however.
But those light blueish tumbled Opalites are man made.
