Is there an easy process to cut diamonds, perhaps a dremel tool or lasers
I was think of buying a dremel tool with Diamond blades but was told that it would not cut the rough diamonds I have. What techniques are there
employed by chemists and gemologists

Diamonds are generally cut with Diamonds.
Cleaving is a highly skilled art, where the cutter whacks one diamond against the other along a known cleave-line, where they know the diamond being
cut will probably split in this process.
Spinning the diamond against a fixed diamond can be used to shape them (both) into some round shape by abrasion.
Laser cutting also works.

Somewhat reminiscable of the flint processing our ancestors did, no? 
I bet one of those H. habilis would be very experienced in seeing and using the cleave lines of a diamond too.

cutting diamonds is done by cleavage with a hammer and specialized chisel

Mercury can also be refined electrolytically.
Because it does not require heating it might perhaps be a less risky way of purifying Hg than distillation. It would involve soluble mercury salts,
however.

Diamonds may be cut or faceted by other diamonds, along certain planes.
Other materials are actually harder than diamonds (or so I have been told). And, could thus do the job. Maybe.
Boron Nitride? I'll check. I checked. Greater compressive strength.
But, how does that translate into abrasive power?
