Round Cut 4 Prong & Cushion Halo Lab Diamond Ring With Half Pave Band

Expertly crafted in polished platinum, this elegant ring features a brilliant round lab diamond held by neat four prongs to maximize light flow and fire. A plush cushion-shaped halo encircles the base of the center stone, amplifying its luminous sparkle with a soft rounded silhouette. The slender band is adorned with half pave micro accent stones that deliver consistent delicate shimmer on the front while keeping the inner band smooth for comfy daily wear. Combining classic solitaire structure with romantic cushion halo detailing, this refined design balances dazzling glamour and practical wearability, ideal for engagement and milestone celebrations.
