Couture Round Diamond Engagement Ring ENG-0488RThe 0488R is an 18k yellow gold round brilliant engagement ring that earns its place in Verragio's Couture Collection. Shared prong diamonds in a riviera style band, a cathedral foundation and a diamond bridge head beneath the crown, each decision in the setting serving the center stone. At 0. 73 carats of accent diamonds and a signature crest at the base, it's a solid understated, refined round diamond engagement ring.
