Onyx Diamond Halo Engagement Ring in 18k White Gold.  A modern take on a traditional design, this beautiful ring obtains aesthetic appeal and visual energy by utilizing highly contrasted onyx and diamonds. This distinction works to emphasize the lovely dancing appearance of refracted light. This piece features a gorgeous .80 carat brilliant cut diamond, prong set in 18k white gold with a halo of onyx and small accent diamonds. Its a striking piece that is still neutral  in color so it would work with everything.
