Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender beam that dances across the hand. This three-stone engagement ring in platinum frames a 12 x 6 mm marquise center with two gently tapering side stones, creating a quiet narrative of balance and grace.

Crafted in our Williamsburg studio, the platinum band is polished to a satiny finish that feels cool and substantial against the skin. The low-profile setting secures each stone with delicate prongs, allowing light to flood the facets while maintaining everyday wearability. The ring’s subtle curvature follows the natural line of the finger, offering a comfort fit that invites daily presence.

Each diamond is lab-grown, embodying clarity and brilliance without the environmental cost of traditional mining. This ethical choice aligns with a commitment to sustainable luxury, quietly woven into every detail.

Designed for those who appreciate refined geometry and romantic symbolism, the marquise shape elongates the finger, lending an elegant silhouette that pairs beautifully with stacking bands or worn solo. Its slender profile slips easily under gloves or sleeves, making it a seamless companion to an active lifestyle.

Should you need a custom fit, resizing is available with care to preserve the ring’s structural integrity and finish. Typical lead times reflect our hands-on approach to quality and detail.
