Lab-Grown Diamond Engagement Ring

Fingers curl gently around a heart-shaped silhouette, its soft curves catching the light like a whispered promise. This three-stone semi-set engagement ring in 18K yellow gold awaits your choice of a 5 x 5 mm heart-cut diamond, a shape that blends tender symbolism with a delicate, sculptural presence.

The warm glow of the yellow gold band is finely polished to a satin finish, designed with subtle tapering that cradles the center stone while balancing two smaller side gems. The low-profile setting ensures everyday comfort, allowing the ring to nestle close to the hand without catching or shifting.

Each piece is crafted in our Williamsburg studio, where precision meets quiet artistry. The semi-set foundation invites your personal selection of a lab-grown diamond, reflecting our commitment to ethical sourcing and sustainable luxury.

Ideal for those who cherish romantic detail and a ring that feels as natural as it looks, this design suits slender to medium finger shapes and layers beautifully with a slim wedding band. Its modest height and smooth edges make it glove-friendly and perfect for daily wear.
