Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, graceful shadow that mirrors the hand’s natural lines. This semi-set solitaire ring features an 8 x 4 mm marquise center, chosen for its elegant taper and subtle drama.

Crafted in warm 18K rose gold, the band is shaped for comfort and low profile, designed to sit close to the finger without catching. The mounting’s precise prongs cradle the stone securely while allowing light to flood its facets, enhancing the signature brilliance of the marquise cut.

Each lab-grown diamond is ethically sourced, offering clarity and sparkle without compromise to the environment. This ring’s refined silhouette suits those who appreciate a sleek, modern aesthetic with everyday practicality.

Its slender band pairs effortlessly with other stackable rings or stands strikingly alone, ideal for hands seeking elongation and subtle sophistication. The low-profile setting ensures ease of wear, even under gloves or daily tasks.

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