Answer 1

Silicon carbide (moissanite) is indeed very hard and applicable for industrial use, but is rare. Yes, you can make it in a lab but industrial scale diamonds (dirt cheap compared to jewelry diamonds) are overwhelmingly plentiful in the ground and do not require any lab-type environments to produce.

You can buy packs of diamond bits for little more than tungsten carbide bits from suppliers and they supply is immense.
