[meteorite-list] Lunar diamonds (was Kalahari 008 and weathering)

[Randy Korotev]

No diamonds have been seen, to my knowledge.  The Moon contains very 
little carbon.  Again, most of the carbon on the lunar surface comes 
either from carbonaceous chondrites or is implanted by solar 
wind.  Nowhere is the C concentration high enough to make a diamond 
by impact pressure.
