Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that feels both intimate and bold. This semi-set halo engagement ring in 18K white gold frames a 6 x 3.5 mm marquise center stone, inviting you to choose a lab-grown diamond that balances architectural grace with a whisper of vintage romance.

Crafted with a low-profile halo setting, the ring offers a subtle lift that enhances sparkle without adding bulk, making it comfortable for everyday wear. The polished 18K white gold band is smooth to the touch, designed to sit close to the finger with a refined comfort fit that pairs effortlessly with wedding bands or stackable rings.

Each piece is finished by hand in our Williamsburg studio, where precision meets quiet artistry. The halo’s delicate prongs are carefully inspected to secure your chosen stone while allowing maximum light to pass through, amplifying the marquise’s signature brilliance.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, which offers clarity and beauty with a smaller environmental footprint. This ring suits those who appreciate a blend of classic form and modern sustainability, especially for hands that favor slender, elongated shapes.
