Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of an 11 by 9 mm oval diamond poised to catch light with every movement—its elongated silhouette subtly elongates the finger, offering a graceful statement without excess.

This semi-set halo ring foundation is crafted in warm 10K rose gold, chosen for its soft glow and enduring strength. The low-profile setting ensures the ring sits close to the hand, minimizing snagging while maximizing comfort for daily wear. Each band is meticulously finished by hand in our Williamsburg studio, with smooth edges and a comfort fit that invites effortless stacking or solo elegance.

Our commitment to sustainability is reflected in the lab-grown diamond center this mounting awaits—offering clarity and brilliance with a significantly reduced environmental footprint.

Designed for those who appreciate subtle sophistication, this setting complements the oval’s natural elongation, ideal for slender or average finger shapes. Its halo frame will enhance the center stone’s presence without overwhelming, making it a versatile choice for everyday life and special moments alike.

Should you need resizing, our Brooklyn studio provides precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
