Possible meteorite?

Any experts? I know it's unlikely but those pits resemble those on other stony meteorites.
about 9 inches long; 4-5 inches wide.
Weak attraction to magnet
Pits on all but one side.
No vesicles
Lighter Interior but very plain- no chondrules or metal flecks
Rust spots
Tiny dark amber and greenish colored crystals visible with hand microscope
Brownish gray streak at first; interior no streak
Gray powder attracted to magnet
Lots of volcanic activity in area-basalts and other magnetic rocks nearby.
Specific Gravity 2.86 based on the water bucket test

Of all the posts I've read on TNet, this is one of the most promising. Tiny amber or green crystals could be literal crystals like a Palasite. If you have not already searched for these, it is time to do so.
So...not saying it is, but definitely not ruling it out of the running.

The green crystals could be peridot (olivine) but the SG is too light. Normal 7.3-7.8. Hardness = 4.

Thanks Tuberale! There are a few red flags (like the specific gravity hvhacker mentions below) but I'm not giving up yet.

Thank you Hvhacker- The specific gravity is definitely a con, but I read that some of the more porous meteorites have lower specific gravities. Definitely an interesting rock either way- would love to know how the exterior regmaglypt-looking indentations could form on a terrestrial rock. If it was from water, I'm assuming it would only be on one side, maybe two. If bubbles in magma, then there would likely be vesicles.

Pallasites have lower SG.

Thanks Tuberale! There are a few red flags (like the specific gravity hvhacker mentions below) but I'm not giving up yet.
Sorry I mis-spelled Pallasite earlier. I believe this is still a possibility. S.G. will be determined by the number and size of olivine crystals in the matrix.

Thanks Tuberale- The olivine crystals, if that's what they are, are tiny, only visible with a hand lens. Regarding the specific gravity, it's in the range of some Lunars (the odds are a million to one but I'm enjoying the fantasy!).

Very interesting piece! Is there a mineralogy club or collage w/geologist near you to verify?

Hope to hear more about this piece and crossing my fingers for you!

Like for me is too dark inside, but outside color is promising. In my opinion 70% meteorite wrong
