Two-Tone Pave Diamond Ring in 18k Yellow White Gold.  This modern diamond cocktail ring features 1.46 carats of round brilliant cut diamonds set in 18 karat yellow and white gold. The striking design contains two elements of white and yellow gold swirling around one another, the white gold containing the pave diamond cluster. While this ring does have a large look, the smooth contours temper that and make this ring more suitable for everyday wear.
