Why this rock is probably not a meteorite:
This rock resembles an impact breccia, so it might be a meteorite.
Lunar impact breccias typically have clasts of different kinds of
rocks, as does this rock. In asteroidal regolith breccias, on the
other hand, the clasts would all be similar.
A suspicious aspect of this rock is the sides are too straight. That
feature appears to be natural, although it's really impossible
to to tell from this photo. Meteorites would never have such flat
side naturally (however, see no. 176). Also,
some of the clast appears to be sedimentary
rocks, although that is also impossible to determine from a photo.
I am unaware of any brecciated meteorite that has translucent green
clasts like this.
