Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that stretches gracefully across the finger. This halo setting frames the 12 x 6 mm lab-grown marquise with a delicate circle of pavé stones, enhancing its tapered drama without adding bulk.

Crafted in platinum, the ring balances strength with a subtle sheen, its low-profile setting designed for everyday wear. The band’s smooth comfort fit and secure prong work ensure the diamond sits close to the hand, minimizing snagging and maximizing ease for daily life.

Each diamond is ethically cultivated in a controlled environment, reflecting Haejin Jewelry’s commitment to sustainable luxury without compromise. The halo’s precision pavé setting is hand-finished in our Williamsburg studio, where every detail is inspected for lasting brilliance.

Ideal for those who appreciate architectural elegance with a modern edge, this ring complements slender fingers and elongates the hand’s natural lines. Its refined silhouette layers effortlessly with wedding bands or stackable rings, maintaining a sleek profile under gloves or jewelry.

Resizing is available to ensure a perfect fit, with typical lead times aligned to our bespoke studio process. Care involves gentle cleaning to preserve the platinum’s soft glow and the diamond’s crisp facets.
