My DH may be buying me a monogram pendant for Valentines Day. Our local jeweler has been doing the 3 letters cut out in a circle (not on a disc) surrounded by a circle border of pave diamonds. I just found out that he will start to do them in a heart shape bordered by pave diamonds as well. Which do you think is prettier - circle or heart? He makes in 2 sizes but I know I want the smaller which may be a tad bigger than 1/2 dollar. The large size is way bigger than what I want. TIA!
