Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set engagement ring frame awaits your choice of a 7 x 3.5 mm marquise center, designed to showcase the stone’s distinctive tapered drama.

Crafted from warm 18K rose gold, the band offers a subtle glow that complements the diamond’s sharp silhouette. Its low-profile setting ensures the ring sits close to the finger, balancing presence with everyday comfort. The smooth finish and secure prong arrangement provide durability without bulk, making it an ideal companion for daily wear.

Each piece is thoughtfully created in our Williamsburg studio using lab-grown diamonds, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

The slender band suits hands that appreciate refined elegance and works well alongside stackable rings or a wedding band. Its modest height fits comfortably under gloves or sleeves, perfect for an active lifestyle.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s integrity and finish.
