Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, tapered brilliance that draws the eye along the finger’s natural line. This semi-set halo engagement ring in platinum frames a 10 x 5 mm marquise center with a delicate circle of pavé stones, enhancing its fiery sparkle without adding bulk.

Crafted for everyday elegance, the low-profile setting keeps the ring close to the hand, reducing snagging while the polished platinum band offers a cool, substantial feel. Each element is meticulously finished in our Williamsburg studio, where precision meets comfort in a design that balances architectural grace with wearability.

Our lab-grown diamonds reflect a commitment to ethical sourcing and environmental mindfulness, offering clarity and fire without compromise.

The slender shape and halo detail suit hands that appreciate refined drama and a ring that layers effortlessly with wedding bands or stackable styles. Its comfort fit and secure mounting make it a practical choice for daily wear, especially for those who favor a sleek silhouette.

Should you need resizing, our in-house artisans ensure a seamless adjustment without disrupting the ring’s integrity. Typical lead times accommodate careful handcrafting and quality inspection.
