Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 13 x 13 mm cushion diamond, its gentle glow unfolding like a whispered promise. This solitaire semi-set balances the warmth of 18k yellow and 18k yellow and platinum with the cool gleam of 18k yellow and platinum, a fixed two-tone embrace that frames the stone with quiet contrast.

Crafted in Williamsburg, the band’s low-profile setting ensures the diamond sits close to the finger, offering everyday comfort without sacrificing presence. The smooth shank curves gently, designed for a natural fit that welcomes stacking or solo wear. Each piece is meticulously finished by hand, inspected under magnification to meet exacting standards.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromise on brilliance or clarity.

This ring suits those who appreciate subtle drama—the cushion cut’s soft vintage glow complements a range of hand shapes, especially elongating shorter fingers with its balanced proportions. Its semi-set nature invites you to select a center stone that resonates personally, making the design uniquely yours.

Resizing is straightforward, handled in-studio with care to preserve the integrity of the two-tone finish and setting.
