I have been fortunate to have seen, photographed, and chemically
analyzed practically every lunar meteorite that has ever been
found. I still can't identify a lunar meteorite "just by looking" at
it, however, and I believe that no one else can, either.

I know that some terrestrial rocks from northwest Africa have been
sold as lunar meteorites:


I myself bought an alleged lunar meteorite from an experienced and
respected European dealer who must, I assume, have obtained it from a
"local" dealer or finder. The sample turned out to be a howardite.

I'm willing to believe that the local dealers perhaps believed these
various stones were lunar meteorites. Nevertheless, they clearly
didn't do the obvious, as Greg suggests, and submit a type specimen
for an expert to verify first. For what it's worth, I have never
been sent a sample of a lunar meteorite by a northwest African dealer
with a request to verify its authenticity.

caveat emptor,
Randy Korotev
