Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a cushion-cut diamond, its gentle glow poised to become the centerpiece of a story yet to unfold. This three-stone semi-set ring in 14K yellow gold awaits your choice of an 8 x 8 mm cushion diamond, offering a balance of vintage warmth and modern artistry.

Crafted in our Williamsburg studio, the band is shaped for everyday wear with a subtle comfort fit and a low-profile setting that nestles close to the finger. Each curve and facet is meticulously finished by hand, ensuring the metal’s buttery sheen complements the diamond’s soft brilliance without distraction.

Our commitment to sustainability is reflected in the lab-grown diamond option, providing clarity and sparkle with a lighter environmental footprint.

The design suits those who appreciate a classic silhouette with a tactile presence—its three-stone layout adds dimension without bulk, making it ideal for stacking or wearing solo. The 14K yellow gold band feels warm against the skin, and its modest height slips easily beneath gloves or sleeves.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s integrity and comfort.
