Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond catches the eye with its tapered points and graceful curve, creating a subtle elongation of the finger. This semi-set solitaire ring in 18K white gold offers a refined foundation, ready to showcase a 9 x 4.5 mm center stone with precision and balance.

Crafted in Williamsburg, the band is designed for everyday wear with a low-profile setting that sits close to the finger, minimizing snagging while maintaining a confident presence. The smooth finish and comfort fit ensure it feels as natural as it looks, while the secure prong structure prepares to cradle the marquise stone without overwhelming its delicate shape.

Each piece reflects a commitment to ethical jewelry, featuring a lab-grown diamond that combines clarity and brilliance with a reduced environmental footprint. This choice aligns with a sustainable approach to fine jewelry, thoughtfully made for modern life.

Ideal for those who appreciate architectural elegance paired with practical design, this ring complements slender fingers and pairs well with stackable bands or a wedding band of similar profile. Its semi-set state invites personalization, allowing you to select a center diamond that resonates with your vision.
