I am considering a tension ring for my fiance, however, she has an extremely small ring size 3 3/4, and I am afraid that it will look foolish or not to proportion. In addition, I am unsure what carat would be too large for this ring size in a tension setting or traditional setting. I am looking at a .52 eightstar and a kretchmer setting, but am considering a .76 as well for a traditional setting. Any help would be greatly appreciated!
