Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring in 18K white gold offers a refined foundation for a 6 x 3.5 mm center stone, framed by delicate accent diamonds that enhance its slender profile without adding bulk.

Crafted with a low-profile setting, the band sits close to the finger, ensuring comfort for everyday wear and ease beneath gloves or sleeves. The smooth finish and precise prong work reflect careful hand inspection, balancing security with elegance.

Each diamond is lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Designed for those who appreciate architectural grace and subtle sparkle, this ring complements slender hands and pairs effortlessly with stackable bands or wedding rings of varied styles.

Resizing is available to ensure a tailored fit, with typical lead times reflecting our Brooklyn studio’s dedication to craftsmanship.
