Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of this marquise diamond, it casts a delicate, tapered shimmer that seems to dance with every movement. Nestled within a halo of finely set pavé stones, the 8 x 4 mm center sparkles with a refined brilliance, framed by a platinum band that balances strength with subtle elegance.

Crafted in our Williamsburg studio, the ring features a low-profile halo setting designed for daily wear, offering a comfortable fit that rests gently against the finger without catching. The platinum’s cool sheen complements the diamond’s fiery facets, polished to a smooth finish and inspected meticulously to ensure lasting beauty.

Each diamond is lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire.

This engagement ring suits those who appreciate a blend of vintage-inspired romance and modern craftsmanship—its slender shape elongates the hand gracefully, while the halo adds a whisper of glamour that pairs effortlessly with stacking bands or a wedding ring.

Should you need resizing, our in-studio experts provide precise adjustments to ensure your ring fits perfectly, with care instructions tailored to preserve its brilliance over time.
