Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a subtle arrow across the finger. This semi-set halo ring, crafted from cool 10K white gold, frames a 9 by 4.5 mm center stone with a delicate circle of pavé accents that amplify its sculptural elegance.

Each band is hand-shaped in our Williamsburg studio, polished to a satin finish that balances refined shine with everyday resilience. The low-profile halo setting ensures the ring sits comfortably beneath gloves or alongside stackable bands, designed for seamless wear from morning light to evening glow.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and brilliance—an ethical choice that honors both craft and conscience without compromise.

Ideal for those who appreciate architectural grace with a touch of vintage charm, this marquise halo complements slender fingers and elongates the hand’s natural lines. The semi-set design invites you to select a center stone that resonates personally, making each ring uniquely yours.

Should you need resizing or prefer a custom adjustment, our Brooklyn atelier offers attentive care with typical lead times of four to six weeks.
