Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, its tapered points tracing a delicate silhouette across the finger. This 12 x 6 mm center stone is embraced by a halo of finely set pavé diamonds, each bead meticulously placed to amplify the gem’s fiery brilliance without overwhelming its architectural grace.

Crafted in warm 14K rose gold, the band’s subtle sheen complements the diamond’s icy clarity. The low-profile halo setting ensures the ring sits comfortably beneath daily gloves or sleeves, while the smooth finish and rounded edges offer a gentle feel against the skin. Each ring is hand-finished in our Williamsburg studio, inspected under magnification to meet exacting standards of symmetry and polish.

Our lab-grown diamonds are chosen for their ethical origin and environmental mindfulness, reflecting a commitment to sustainability without compromise on beauty or durability.

This design suits those who appreciate a statement piece that remains wearable—its slender shape elongates the finger, while the halo adds a vintage-inspired glow that pairs effortlessly with stacking bands or a wedding ring.

Should you need a custom fit, resizing is handled expertly in-house to preserve the integrity of the setting and metalwork.
