Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that stretches gracefully across the finger. This semi-set halo engagement ring in 14K yellow gold frames a 6 x 3.5 mm marquise center with a delicate halo, enhancing its tapered drama without adding bulk.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease beneath gloves or sleeves. The polished 14K yellow gold offers a warm glow, while the halo’s precise pavé setting secures smaller stones with technical assurance, ensuring durability and sparkle. Each piece is hand-finished and inspected in our Williamsburg studio to meet exacting standards.

Our diamonds are lab-grown, offering the clarity and fire of mined stones with a lighter environmental footprint. This ring suits those who appreciate a refined silhouette that elongates the hand and pairs effortlessly with stackable bands or a wedding band.

Resizing is available to ensure a tailored fit, and the semi-set design invites you to select a center stone that reflects your unique vision. Typical lead times reflect our commitment to craftsmanship without rush.
