Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger, accentuated by a marquise diamond’s tapered silhouette catching light with every movement. This semi-set solitaire ring awaits your choice of a 6 x 3.5 mm center stone, offering a refined balance between presence and wearability.

Crafted in 10K yellow gold, the mounting features a low-profile setting designed for everyday comfort and resilience. The slender band curves gently, ensuring the ring sits close to the finger without catching, while the secure prongs cradle the marquise shape to highlight its distinctive pointed ends.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every detail to meet exacting standards. The choice of a lab-grown diamond aligns with a commitment to ethical jewelry, reducing environmental impact without compromising brilliance.

Ideal for those who appreciate architectural elegance paired with practical design, this ring complements slender to medium finger sizes and layers seamlessly with wedding bands or stackable rings. Its subtle profile makes it glove-friendly and suited for daily wear.
