Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a slender finger, crowned by a marquise diamond’s tapered silhouette catching light with every movement. This semi-set engagement ring offers a refined foundation in 18K yellow gold, designed to cradle a 6 x 3.5 mm marquise stone with precision and grace.

Crafted in Williamsburg, the band’s low-profile setting ensures the diamond sits close to the finger, minimizing snagging while maximizing comfort for daily wear. The smooth finish and balanced weight create a natural feel, while delicate accent details frame the center stone’s pointed elegance without overwhelming it.

Each piece reflects a commitment to ethical jewelry through the use of lab-grown diamonds, combining clarity and sustainability without compromise. The warm glow of yellow gold complements the marquise’s dramatic shape, ideal for those who appreciate subtle statement and architectural form.

Designed for hands that value both style and practicality, this ring fits comfortably beneath gloves and stacks effortlessly with complementary bands. Its semi-set nature invites you to select a center stone that speaks personally, making the design uniquely yours.
