Not a gem expert but it would seem that yes big clear ones are rare and so will always be expensive. But the kind of diamonds we "average joe's" buy aren't that rare and are expensive only due to the DeBeers's marketing machine.

Diamonds Big clear ones are rare
Rare only because they are not useful enough to make if it were not for the advertising. Vapor deposit carbon finished by zone refining could produce as big and clear a diamond as you may want (at least up to 3 inches or so now). It's just not cost effective because as you know, DeBeers could just dig them up for less money than they cost to make, and nobody outside the jewelry business has a need for them.
