Oh c'mon now.. my ring isn't THAT big. Personally, that stuff is a joke. Logically, what the hell do you do with something so big? You'd obviously never be able to wear it..? Keep it under lock and key? And with the money it takes to buy it I can think of 1,000,000,000,000 other things to buy. 2 cts, E clarity for a center stone is plenty.
