[meteorite-list] Size of diamonds in meteorites

[Adam Hupe]

Dear List,

Tell me if I am wrong thinking it is the diamonds in Ureilites that make
them so hard to cut.  Why are Ureilites so hard to cut if the diamonds are
too small to interfere with the cutting and polishing processes?

Kind Regards,
