Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated curves of an oval diamond, it casts a gentle glow that seems to stretch beyond the stone itself. This semi-set engagement ring offers a 6 x 4 mm oval center, poised to become the heart of your custom design.

Crafted in cool, enduring platinum, the split shank delicately embraces the center stone with subtle accent diamonds that catch light from every angle. The low-profile setting ensures a comfortable fit for daily wear, while the smooth finish reflects the meticulous handwork of our Williamsburg studio artisans.

Each lab-grown diamond is chosen for its clarity and brilliance, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

Designed for those who appreciate refined romance, this ring’s slender band and graceful split shank complement slender fingers and stack effortlessly with wedding bands or delicate bracelets. Its modest height makes it glove-friendly and ideal for everyday life.

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