Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette that seems to stretch the hand itself. This semi-set solitaire ring in warm 14K yellow gold awaits your choice of a 10 x 5 mm marquise center, its setting crafted to cradle the stone securely while maintaining a refined, low-profile presence.

Each band is hand-shaped and polished in our Williamsburg studio, with a smooth comfort fit that slides on effortlessly and wears well beneath gloves or alongside other stackable pieces. The delicate prongs are tapered to highlight the diamond’s dramatic shape without overwhelming its natural brilliance.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and sparkle with a lighter environmental footprint.

This design suits those who appreciate architectural elegance paired with everyday practicality—ideal for slender fingers or anyone seeking a ring that balances statement and subtlety.

Should you need resizing, our in-house artisans ensure a precise adjustment without compromising the ring’s integrity or finish.
