Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender shadow that seems to stretch beyond the hand. This semi-set solitaire invites you to select a 9 x 4.5 mm marquise stone, known for its dramatic taper and ability to visually lengthen fingers with refined elegance.

Crafted in 14K yellow gold, the mounting features a low-profile design that sits close to the finger, balancing presence with everyday comfort. The slender prongs secure the stone while allowing maximum light to enter, enhancing brilliance without bulk. Finished by hand in our Williamsburg studio, the band offers a smooth, comfort fit ideal for daily wear and effortless stacking.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire.

This solitaire suits those who appreciate architectural grace paired with practical design—its slim silhouette works well on slender to medium fingers and pairs seamlessly with wedding bands or stackable rings. The low profile ensures it slips easily under gloves or sleeves.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s integrity and finish.
