Coastal Crescent Cushion Bloom Diamond Engagement Ring P103The cushion bloom on the P103CU frames a round center stone in yellow gold, the softened square halo sitting close with milgrain edging and 0. 25 carats of G, VS diamonds across the setting. The slim pav band tapers toward the crown and the Coastal Crescent gallery beneath it carries the collection's signature wave detail. A 14k gold diamond engagement ring that wears beautifully to a proposal and just as naturally to everything that follows.
