Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, evoking a quiet drama that feels both bold and refined. This solitaire semi-set in 18K yellow gold offers a streamlined foundation, crafted to cradle a 10 x 5 mm marquise center stone with precision and subtlety.

The band’s low-profile setting ensures the ring sits close to the finger, reducing snagging and enhancing comfort for everyday wear. Each curve is hand-finished in our Williamsburg studio, polished to a soft glow that complements the warm gold without overwhelming the diamond’s sharp geometry.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, which provide exceptional clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate architectural elegance and practicality, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its comfort fit and modest height make it glove-friendly and ideal for a life in motion.

Should you need adjustments, resizing is handled expertly in-house to maintain the integrity of the design. Typical lead times for completion are communicated clearly during your consultation.
