I am looking into a setting where the diamonds on go all the way around, but I''ve been told that it is not the best idea to have them this way. Since the center stone is always on top, she will always be hitting the same stone underneath, and they will eventually dislodge. Is this true? Would it be safer/wiser to look at someting where the diamonds went half way around, especially with prong settings, similar to an eternity band? Thanks
