Double Halo Round Diamond Engagement Ring MR2461The MR2461 is an 18k white gold engagement mounting where 0. 44 carats of G, VS2 round brilliant diamonds are distributed across two halo rows and a diamond set shank leading to the gallery. The layered framing gives a round brilliant center stone presence and the vintage inspired detailing carries that same considered quality through the band. A setting built for a proposal worth remembering.
