No, it's not a meteorite, lunar or otherwise. Vesicles are rarely seen in meteorites and, when present, usually small and sparse. For some lunar meteorites, the fusion crust can be highly vesicular, but such crusts are thin (no more than about 2mm) and usually have a dark glassy appearance that's very distinct from the interior.

Oke, but i want to mention that the photo's i posted where not very good for indentification. Here is a new photo of my stone and a photo of a real lunar. My rock has voids that are filled with wat looks like calcium just like some lunars as seen on the second photo. And of course my stone is a weathered and old specimen but it has what looks like a thin brown cust.

Sorry, but the image of the lunar meteorite NWA 11273 doesn’t show what you think it shows. The matrix (as opposed to the thin fusion crust) of that meteorite and other lunars contains only tiny vesicles. NWA 11273 is a feldspathic breccia and the inclusions seen are clasts formed from repeated impacts on the lunar surface. The light-coloured clasts are anothositic rock and the dark clasts are basaltic.

Some lunars, particularly ancient specimens found in hot desert areas, do indeed have white and light-coloured calcite (not calcium) as a secondary alteration product from interaction with earth’s atmosphere and terrestrial fluids. However, in lunars, it’s not vesicular but arises in fractures and veins.

Your rock is not a meteorite.

What you have, in my opinion, is common limestone with quite a few fossilized mollusk shells easily visible in all the images of your first post. Quite a bit like the limestone found all over central Texas.

Time for more coffee.

I don't know what you see in the first posted photo's but it does not contain any molusk shells. The white you seen is a filled up vug with a white mineral and i showed it to a geologist and he has said it is not limestone nor is it a fossil and it does not contain any fossils. There is a large augite crystal in one of the vugs. I could not cut it there so at home i hit it with my hammer and it is dark blue/black inside. It does not atract a magnet. Can someone tell met what is could be when it is not a meteorite.?

here is a photo of the augite crystal in the white filled vug.

What did you use to try to cut it?

i could not cut it because they where moving to a different location (natural historie depot). So i have hit a piece of with a small hammer. And it is quite a hard stone.

"natural historie depot"
Explain to me what is that?

Place sounds interesting.

Where abouts were they located before they moved?
