Possible. But the tests performed are not conclusive. Need to cut or grind a window to see the interior matrix.

Ok.. Thank you so much I will look up the best way to do that I'm so scared of damage I might cause but I'm sure there gotta be a safe way to do that

Cutting with a diamond blade is the way to go to minimize loss. If you ever expect to have this certified authentic then you are going to have to cut off a 20 gram sample and send off for analysis. So if that is the plan, be sure to cut off a large enough section. If it has potential, you can send in the sample. If not, then it's just another rock.
As for a window approach, that will not be viewed as damage on a single stone like this. It's a normal field procedure hunters use to do a preliminary analysis. A diamond file or power sander on a small section should be sufficient to get through the crust and show the interior.
If this was a complete stone with great features like an oriented individual, then I'd pass on the window process. But if this is genuine, then it is a fragment off of a larger stone.

This is exciting I have been trying to figure out where would be the spot to cut If you dont mind giving me some more advice id like to take some more photos of the spot im thinking to cut . It has a few hairline cracks that kinda look like they dont want to be awoken lol .. It is for sure not a complete stone You cans see where the fault line runs and then its like a clean break where you can see the seperation .. im gonna get a good photo of that cause im thinking i should break it from that area every part of it is so rare in a completely different way from another part, and the way it fits into your hand ahhhhhh i will love it no matter what it is

Fault lines says it's a JUSTA...just-another-rock...
If you slab it for testing, might use a ceramic tile saw...

It looks awfully angular (sharp edges) to be a meteority but a good flat grind and acid etch will help with further analysis.

Looks like a lump of magnetite-rich rock.
But as other say, if its a stoney meteorite it would tend to be glassy on the surface where the outside has melted during entry. This looks too angular. If I would hazard a guess I would say it is not a meteorite and probably an iron-rich sedimentary rock, a shale to be more specific.
Ps
I studied and worked as a geologist in the past, but my knowledge on iron rich rocks may be a little 'oxidised'

If it were me, I'd determine the best perspective and then cut on the other side of the rock. Easy to take a corner off rather than a whole face. As for the angular features and fault lines, what that means is it has angular features and fault lines. When weathering occurs, fractures occur over many years due to freeze / thaw cycles. And then the original rock can fracture. I've attached some pictures of angular meteorites with numerous fault lines from Northwest Africa.

There is one thing that can be meteorite like, sometimes called a slag meteorite. I have 2 of them and the 3rd sent for assay, but it was never returned. Yes, people find slag rocks, try to sell them as meteorites. Mine assayed as greater than 5% metallic iron, 1% titanium, I think also copper and manganese. Try google for slag meteorite. Or try this link.

Not quite sure but meteorites (typically) cant form flat sided in space. Not sure though

Looks like bubblie basalt. Slag is usually found near industries.
Most meteorites iron content will be in the 90% range with the rest being nickel and other stuff.
Slag meteorite sounds like an oxymoron.
