I have a size 7, short, pudgy looking ring finger. I would like to upgrade my ering in the next few months. I currently wear both a round and a princess cut solitaire with my 6mm wide platinum wedding band. I really like both princess cut and cushion stones, but I am not sure if they look best with fingers that are not long and slim. I would like to have a solitaire that is between 2-3 cts with a side stone on each side of the center diamond. Which diamond shape would look best with my fingers?
