Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that feels both intimate and expansive. This three-stone semi-set engagement ring frames a 12 x 6 mm marquise center with two gently tapering side stones, each nestled in a refined 10K white gold band that balances subtlety with presence.

Crafted in Williamsburg, the ring’s low-profile setting ensures a comfortable fit for daily wear, while the polished white gold shank offers a cool, smooth touch against the skin. The semi-set design invites you to select a center stone that resonates with your vision, allowing for a personalized expression of commitment.

Each lab-grown diamond is chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromising on radiance. The elongated marquise shape lends an elegant elongation to the finger, ideal for those who appreciate a blend of classic form and modern refinement.

Designed to complement a variety of hand shapes, this ring’s slender band and secure prongs make it glove-friendly and stackable with other bands or wedding rings. Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio.
