Lab-Grown Diamond Engagement Ring

When light catches the delicate curves of a heart-shaped diamond, it reveals a quiet promise—intimate and unmistakably personal. This semi-set halo ring invites you to select an 8 x 8 mm heart-cut center, its soft silhouette framed by a halo that amplifies every flicker of brilliance.

Crafted in 10K white gold, the band is shaped with a subtle comfort fit, its smooth surface finished by hand in our Williamsburg studio. The halo setting balances presence with wearability, designed low enough to slip easily beneath gloves or stack alongside other bands without catching.

Each piece reflects our commitment to ethical jewelry: the heart-shaped diamond is lab-grown, offering clarity and sparkle with a lighter environmental footprint. This ring suits those drawn to romantic symbolism paired with modern craftsmanship, especially for hands that appreciate a refined yet approachable profile.

Should you need resizing, our Brooklyn atelier handles adjustments with care to maintain the ring’s seamless form. Typical lead times align with our bespoke process, ensuring your ring is made thoughtfully and to exacting standards.
