Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across your hand. This semi-set engagement ring in 18K yellow gold awaits your choice of a 9 x 4.5 mm marquise center, its shape lending a refined, tapered drama that visually lengthens the finger.

Crafted with a low-profile setting, the band sits close to the skin for everyday comfort and ease beneath gloves or sleeves. The yellow gold shank is polished to a soft glow, designed to balance durability with a subtle warmth that complements the diamond’s fiery facets. Accents along the band add a delicate texture without interrupting the sleek silhouette.

Each piece is finished and inspected in our Williamsburg studio, where precision meets quiet craftsmanship. The lab-grown diamond option ensures a clarity and brilliance aligned with sustainable values, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate a refined yet practical ring, this design suits hands seeking a slender, elegant profile that layers well with wedding bands or stackable rings. Its semi-set nature invites you to select a center stone that resonates personally, making the ring uniquely yours.
