Is this a meteorite

[BOXING63]

Hello could this be a meteorite, I find this in the mountains about 6" in the ground with my metal detector, it's not magnetic then three day after that, i found two more in the beach 4" in the sand the first pic is 1"3/4 inch x 1"3/8, and is 29.8 grams, The next pic is 1"1/8 x 3/4 and it's 21.3 grams and the last one is 1"1/2 x 1" it 6.4 grams,

Nope, not meteorites.

First pic resembles slag, not sure about the bottom ones but not meteoritic.

Looks like you may have found a Silver, Platinum or Gold nugget, I don't think it is Slag It may possibly be from a meteorite but I don't think so. Is the sample heavy? Is it soft or scratch easy?

More likely lead and aluminum. But you never know. Definately not a meteorite though.

I don't know. And neither does anyone else. It might be. Most recent meteorites have a fusion crust, caused by melting iron, usually 1-2 mm thick. I don't see one here, but your stone may have been on earth long enough to have lost that.

The first stone is the most interesting to me: it seems to show flow lines, which could be caused by melted material entering the atmosphere. While most meteorites are magnetic, not all are. The ones that aren't are much rarer than those which are, and are often mis-identified because of that.

You have some options here. Most universities have geology departments which can do initial inspection of possible meteorites.

Some laboratories have been set up specifically to test for meteorites. The testing is free, but can take several months.
