Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a subtle sparkle that elongates the finger with quiet elegance. This semi-set engagement ring offers a refined foundation for a 5 x 3 mm marquise diamond, known for its graceful silhouette and delicate drama.

Crafted from 18K white gold, the mounting features a low-profile design that sits close to the hand, enhancing comfort without sacrificing presence. The band’s smooth finish and secure prong setting ensure daily wearability, while delicate accent stones add a whisper of brilliance around the center.

Each piece reflects a commitment to sustainability through the use of lab-grown diamonds, combining ethical clarity with Brooklyn craftsmanship. The ring’s modest height and balanced proportions make it ideal for those seeking a sleek, glove-friendly fit that layers effortlessly with other bands.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s integrity. Typical lead times accommodate custom requests, ensuring your design experience is as thoughtful as the ring itself.
