I am aware of the 4 Cs of diamond quality, but am wondering about pave... settings. Do manufacturers, jewelers, etc. use a lower quality of diamond for pave? I often see reviews of watches or jewelry with pave and people complain about how the diamonds are so tiny. Isn't that what is used in pave settings? And aren't most diamonds of the H-I variety anyway, since the very best diamonds were mined out of the earth ages ago, I don't know if I have seen anything better than G color, maybe an F. I always thought that round cuts were the most desirable, but since I really don't know, I thought one of you jewelry mavens might know her stuff. Thanks.
