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 engagement ring offers a 7 x 3.5 mm marquise center, designed to balance presence with everyday ease.

Crafted in 10K white gold, the mounting features delicate accent stones that frame the center without overpowering it. The low-profile setting keeps the ring close to the hand, reducing snagging and enhancing comfort for daily wear. Each piece is meticulously finished and inspected in our Williamsburg studio to ensure smooth edges and a secure fit.

Our lab-grown diamonds bring clarity and brilliance with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

Ideal for those who appreciate a refined silhouette that elongates the finger, this ring pairs effortlessly with stacking bands or stands alone with quiet confidence. Its comfort fit and modest height make it glove-friendly and suitable for an active lifestyle.

Should you need a custom size, resizing is straightforward and handled with care by our in-house artisans.
