I saw that sizes 4 and smaller and larger-than-average sizes cost extra for the vatche settings. i can understand why larger ones would cost more, because they require more metal. why do the smaller ones cost more? does the crown (?top of the ring setting?) become smaller as the ring size goes down? I''d hope that the top of a size 4 would be proportionately smaller than the top of a 6 or larger. Can anyone explain?
