Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This semi-set solitaire ring features a 5 x 3 mm marquise center, chosen for its graceful taper and vintage-inspired allure.

Crafted in 14K white gold, the mounting is designed with a low-profile setting that keeps the diamond close to the hand, minimizing snagging and enhancing everyday comfort. The band’s smooth finish and balanced weight ensure it feels natural for daily wear, while the secure prongs cradle the stone with precision.

Our diamonds are lab-grown, offering a clear, sustainable alternative that reduces environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate refined geometry and a sleek silhouette, this solitaire suits slender to medium finger sizes and pairs effortlessly with stacking bands or wedding rings. Its modest scale and comfort fit make it glove-friendly and unobtrusive.

Should you need adjustments, resizing is straightforward with our in-house Brooklyn studio, where each piece is finished and inspected by hand.
