[meteorite-list] Size of diamonds in meteorites

[stan .]

nanometer - a tiny fraction of the size of the finest grit you would ever 
use to polish a meteorite. strangely enough it's not only carbides and 
diamonds that lead to wearing out lapping medium - i belive you got a piece 
of dho700 from Blaine - try putting a polish on that slice if you havent 
already - the material is as hard as the worst of the worst of ureilites - 
and last time  ichecked there werent any diamonds or carbide found in 
diogenites..
