> HOW THE HELL DO THEY CUT DIAMONDS?!

  If you mean in the first instance when say, a large rough diamond needs to 
be made into several smaller faceted diamonds, well, they 'cleave' the 
rough. Basically, a hammer and chisel are used to smack a rough in half and 
then quarters, etc.

   But if you meant cutting the actual facets, well, with diamond of course. 
;)

   Actually, it's diamond paste. They start with a rough paste and work the 
facets down to a smooth finish with a fine paste and then they use even 
finer diamond paste (or spray) to actually polish the facets.
