Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to whisper of quiet promises. This semi-set halo engagement ring in platinum frames a 6 x 3.5 mm marquise center with a circle of finely crafted pavé diamonds, enhancing its tapered drama without overwhelming the hand.

Each platinum band is meticulously shaped for a comfort fit, its low-profile setting designed to sit gracefully beneath daily gestures. The halo’s subtle sparkle is hand-set by our Brooklyn artisans, polished to a soft sheen that complements the diamond’s glassy facets. This piece balances architectural elegance with wearable ease, ideal for those who appreciate refined detail and enduring comfort.

Crafted with a lab-grown diamond, this ring reflects a commitment to ethical jewelry—minimizing environmental impact while maximizing clarity and light. The marquise’s distinctive shape elongates the finger, pairing beautifully with slender hands or as a striking contrast in a stack of mixed shapes.
