Lab-Grown Diamond Engagement Ring

Morning light catches the subtle dance of five stones poised to frame a round center, its 8.2 mm diameter promising a luminous focal point. This semi-set platinum band offers a modern-minimal silhouette, where clean lines and structural clarity meet quiet confidence.

Crafted in Williamsburg, the platinum shank is polished to a soft sheen, designed for daily wear with a low-profile setting that nestles close to the finger. Each prong is meticulously shaped to secure your chosen center stone while allowing maximum light to enhance its brilliance.

Our commitment to sustainability is reflected in the lab-grown diamond clarity, offering an ethical alternative without compromise on sparkle or integrity.

The five-stone arrangement suits those who appreciate architectural balance and a refined statement, pairing effortlessly with a comfort fit that feels natural whether worn solo or stacked.

Should you wish to adjust sizing, our in-studio experts ensure a precise fit without disrupting the ring’s clean lines.
