Is diamond conductive enough???

Interestingly, diamond has great thermal conductivity and great
electrical conductivity. Can you say heat sink insulators?

Uh, actually diamond is one of the materials with the phonon-carrier
anomaly. It's a great thermal conductor (better than silver) but it's an
electrical insulator.

There are some surface-conductivity phenomena which have only recently been
understood, but the bulk electrical resistance of diamond is very high.
Impurities and intentional additives in synthetic diamonds can alter this.
