I'm wondering if the same thing couldn't be done by placing the pure carbon inside a soccer ball shaped charge of TNT then contain that in a thick enough mold shaped like the presses shown to contain a blast the heat would be tremendous as well as the pressure and a nice boom to go along with it LOl

There actually is a technology to produce synthetic diamond using explosives, though it doesn't give gems -- instead you get detonation nanodiamonds, which are great as a polishing compound.
