Black and white is the order of the day for this soignée ring. Engagement ring, right hand ring - rise to the occasion with this superb diamond ring. Set with a central old European diamond of approximately .70 carats (H-I color; SI clarity), another 20 single cut diamonds add a surround of shimmering light as a trim of black as night onyx tailors the look. With an open work center and pillows of icy white platinum, diamonds and black encircle the ring. All in platinum, the ring dazzles with its unique singularity.
