I am in the process of picking out a semi-mount to go with my new .73 RB hearts and arrows, G, VS2, diamond. The setting that I am looking at has two marquis side stones and will be set like this <>(RB)<>. I have two in mind. One has .12 stones on each side and the other has .25 stones on each side. My dilemma is that I''m afraid that the .12 side stones might be too small and the .25 might be too big and over power the diamond. Once I buy the setting, there are no returns since it is custome made. I was hoping that someone with some experience in designing rings or setting stones can give me an opinion on which would look better proportioned. Any help would be greatly appreciated. Thanks!!!!!!!!!
