Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light like a shard of morning frost. This three-stone semi-set engagement ring frames a 9 x 4.5 mm marquise center with two delicate side stones, all poised on a sleek 10K white gold band that balances modern minimalism with architectural clarity.

Crafted in Williamsburg, Brooklyn, 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. Each element is meticulously finished and inspected in-studio, reflecting a quiet confidence in precision and structure.

Our commitment to ethical jewelry is embodied in the choice of a lab-grown marquise diamond, offering exceptional clarity and brilliance with a reduced environmental footprint.

Designed for those who appreciate clean lines and refined geometry, this ring suits slender fingers and pairs effortlessly with stackable bands or a wedding band of your choice. Its semi-set nature invites you to select a center stone that resonates personally, making the design uniquely yours.
