Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond, its tapered points echoing the graceful arc of a Brooklyn skyline at dusk. This semi-set halo engagement ring foundation in platinum awaits your choice of an 8 x 4 mm marquise center, designed to amplify the stone’s elongated drama with a ring of finely crafted pavé diamonds.

Hand-forged in our Williamsburg studio, the platinum band offers a cool, substantial feel with a low-profile setting that nestles close to the finger, balancing presence with everyday comfort. The halo setting is meticulously finished to catch light from every angle, enhancing the marquise’s signature brilliance without overwhelming its architectural shape.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity with a conscientious footprint.

Ideal for those who appreciate a refined statement that pairs effortlessly with stacking bands or stands alone with quiet confidence. The slim profile and smooth edges make it glove-friendly and suited to a variety of hand shapes, especially elongating narrower fingers.

Should you need resizing, our in-studio experts ensure a precise fit without compromising the ring’s integrity.
