Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This semi-set halo engagement ring foundation in 18K rose gold offers a warm, blush-toned frame, inviting you to select a center stone that will sparkle with refined drama.

Crafted in Williamsburg, the band is polished to a soft sheen, its low-profile halo setting designed for everyday grace and comfort. The rose gold’s gentle glow complements the marquise’s tapered drama, while the halo setting amplifies brilliance without adding bulk. Each piece is meticulously finished and inspected in-studio, ensuring a smooth fit that slides easily beneath gloves or alongside stackable bands.

Our commitment to sustainability is reflected in the choice of lab-grown diamonds, offering clarity and fire with a lighter environmental footprint.

This ring suits those who appreciate a blend of vintage-inspired romance and modern wearability—its slender silhouette elongates the finger, while the halo adds a subtle sparkle that catches the eye without overwhelming.
