Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a delicate, tapered glow that seems to stretch the hand’s silhouette. This three-stone semi-set ring invites your choice of a 6 x 3 mm marquise center, framed by two smaller stones to balance its architectural elegance.

Crafted from solid 18K yellow gold, the mounting is shaped with a low-profile gallery that sits close to the finger, offering a comfortable fit for daily wear. Each prong is hand-finished to secure the stones while allowing light to flood the facets, enhancing the marquise’s signature brilliance. The band’s subtle taper and smooth polish reflect the artisan workshop’s attention to detail, ensuring the ring feels as refined as it looks.

Our commitment to ethical jewelry is reflected in the option to pair this setting with a lab-grown diamond, combining clarity and sustainability without compromise.

Designed for those who appreciate a sculptural yet wearable ring, this setting complements slender to medium finger sizes and layers gracefully with stackable bands or wedding rings. Its modest height makes it glove-friendly and unobtrusive for everyday life.

Should you need resizing or prefer a custom stone cut, our Brooklyn studio offers personalized consultations to tailor the ring to your vision.
