Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette echoing the graceful sweep of a Brooklyn skyline at dusk. This semi-set engagement ring invites you to select a 6 x 4 mm oval center stone, known for its subtle elongation that visually lengthens the finger with quiet elegance.

Crafted from warm 10K rose gold, the band is shaped with a delicate three-stone setting that balances artisanal detail and everyday wearability. Each prong is hand-finished in our Williamsburg studio to cradle your chosen diamond securely while maintaining a low-profile silhouette that slips comfortably beneath gloves or sleeves.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and brilliance without compromise. This ethical choice aligns with a modern approach to fine jewelry, mindful of both origin and impact.

The ring’s slender band and modest height suit those who appreciate subtle sophistication, ideal for stacking alongside wedding bands or wearing solo with ease. Its design accommodates resizing, ensuring a tailored fit that feels natural on the hand.
