the hardest drill I have is HSS Cobolt?

Because diamonds "grind" rather than "chisel".

For drilling stone, there would be no advantage to making a diamond drill
over a TCT drill and it would be a lot more expensive.

You can buy diamond core drills, which, as Dave says, grind their way
through. Beneficial for large holes in stone but that's about all.
