Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone engagement ring balances architectural elegance with intimate craftsmanship, its 7 x 3.5 mm marquise center flanked by two delicately matched side stones.

Hand-forged in platinum, the band offers a cool, substantial feel with a low-profile setting that nestles comfortably against the skin. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the stones sit securely while allowing light to flood every facet. The three-stone design creates a subtle arc that complements the finger’s natural curve, making it equally suited for daily wear or special moments.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Its slender silhouette and smooth comfort fit make it ideal for those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable pieces. The marquise shape’s tapered points elongate the finger, lending a graceful presence that feels both modern and timeless.

Should you need a custom adjustment, resizing is handled with care to preserve the integrity of the setting and metal finish.
