Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond’s pointed tips, casting a slender, luminous silhouette across the hand. This semi-set halo engagement ring offers a refined frame for a 10 x 5 mm marquise stone, designed to amplify its graceful, tapered drama without overwhelming daily wear.

Crafted in warm 14K rose gold with a subtle white gold halo, the band maintains a low profile that slips comfortably beneath gloves and nestles easily alongside other rings. The halo setting, meticulously finished in our Williamsburg studio, balances sparkle with secure prong work, ensuring the center stone’s brilliance endures through everyday moments.

Each piece features a comfort fit shank, shaped to reduce pressure points and enhance wearability. Our lab-grown diamonds provide the same optical precision as mined stones, with a clear ethical advantage—minimizing environmental impact while maximizing clarity and fire.

This ring suits those who appreciate architectural elegance paired with practical design, especially hands that favor elongated shapes or seek a stackable silhouette. The semi-set style invites personal choice, allowing you to select a marquise diamond that resonates most deeply.

Resizing is straightforward, handled carefully in-studio to preserve the integrity of the halo and band. Typical lead times accommodate custom stone selection and finishing.
