Why this rock is probably not a meteorite:
This is a polished, sawn face of a rock. The finder thought that it
resembled some lunar meteorite breccias.
1) The grains are too rounded. On the surface of the Moon and
asteroids, there is no flowing water or blowing wind, so there is
no mechanism to make rounded grains. Impacts of meteoroids on
the surface of asteroids and the Moon tend to make angular rock fragments.
Chondrules in chondritic meteorites are more spherical than this.
2) Meteorites aren't this blue. The blue color may be a photographic
artifact, however.
