Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a 12 x 6 mm marquise diamond, casting a slender, luminous silhouette that gently elongates the finger. This semi-set halo engagement ring in 18K yellow gold offers a refined foundation, designed to cradle your chosen center stone with precision and subtlety.

Crafted in Williamsburg, the band’s low-profile setting ensures the ring sits close to the hand, minimizing snagging while maximizing comfort for everyday wear. The halo setting adds a delicate frame of smaller stones, enhancing brilliance without overwhelming the marquise’s distinctive shape. Each curve and angle is carefully finished by hand, inspected for smooth edges and balanced proportions.

Our commitment to lab-grown diamonds means your ring carries a clarity and sparkle born from sustainable practices, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate architectural elegance paired with practical design, this ring suits slender to medium finger sizes and layers effortlessly with stackable bands or wedding rings. Its comfort fit and low profile make it glove-friendly and unobtrusive in daily life.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the setting’s integrity.
