Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a subtle, tapered brilliance that draws the eye along the finger’s natural line. This semi-set solitaire ring features a 9 x 4.5 mm marquise center, designed to showcase your chosen stone with precision and clarity.

Crafted in 18K white gold, the mounting offers a low-profile silhouette that rests close to the skin, minimizing snagging and maximizing comfort for everyday wear. The streamlined prong setting secures the stone while allowing ample light to enter, enhancing the diamond’s signature sparkle. Each ring is meticulously finished and inspected in our Williamsburg studio, ensuring a refined surface and balanced fit.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining sustainability with exceptional clarity and brilliance.

Ideal for those who appreciate architectural elegance and a sleek profile, this ring suits slender to medium finger shapes and pairs effortlessly with stacking bands or wedding bands. Its comfort fit and modest height make it glove-friendly and practical for daily life.
