Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette across the hand. This 9 x 4.5 mm center stone is framed by a delicate halo, enhancing its tapered drama without adding bulk.

Set in warm 14K rose gold, the ring’s low-profile halo setting ensures it sits close to the finger, balancing presence with everyday comfort. The band’s smooth finish and subtle taper make it glove-friendly and ideal for stacking alongside wedding bands or personal favorites.

Crafted in our Williamsburg studio, each ring undergoes meticulous hand finishing and quality inspection to maintain precise symmetry and secure prong settings. The rose gold’s gentle blush complements the marquise’s sharp geometry, creating a harmonious contrast that feels both modern and intimate.

Our lab-grown diamonds offer the same optical brilliance and clarity as mined stones, with a significantly reduced environmental footprint—reflecting a commitment to ethical jewelry without compromise.

This design suits those who appreciate architectural elegance paired with practical wearability, especially for slender or average finger sizes where the marquise shape elongates the hand gracefully.

Should you need resizing, our in-house artisans can adjust the band with care to ensure a seamless fit. Typical lead time for custom adjustments is two to three weeks.
