Here's one for the romantics. Instead of having two diamonds side by side, the Kissing Diamonds ring sets them end to end (or, more properly, culet to culet) so that the shape of the diamonds from kissing lips. The design is available in a wide variety of styles with a solitaire or three-stone designs in a yellow or white 18K gold settings. The potential for scratching here seems pretty high but My first concern here is that the diamonds would chip but the stones seem to be carefully chosen and matched to avoid potential calamity.
