I am buying a three stone engagement ring (all emerald cut diamonds) but I can see the ring band/setting through the diamonds! The band has three little holes under the cutlets (i think thats the right term) but those little holes dont really help. I''m wondering if Emerald cut diamonds should have an open bottom. I''ve looked on the internet and most of the EC three stone ring settings Ive seen have open bottoms but some do not. My diamond broker says that the "band" I see is really just the "shine of the diamond" and not the actual platinum band, but I think he is full of it. Can you help?
