Light catches the elongated silhouette of the marquise diamond, its tapered points tracing a delicate arc across the finger. This three-stone engagement ring in polished platinum frames a 6 x 3 mm lab-grown marquise with two gently rounded side stones, creating a quiet dialogue of brilliance and shadow.

Crafted with a low-profile setting, the band’s smooth comfort fit ensures it rests naturally for daily wear. Each prong is meticulously finished by hand in our Williamsburg studio, securing the stones while allowing light to dance freely through their facets. The platinum’s cool sheen complements the diamond’s icy clarity without distraction.

Our commitment to sustainability is reflected in the lab-grown diamond’s traceable origin, offering a conscious alternative without compromise on sparkle or integrity.

Designed for those who appreciate refined elegance, this ring’s slender profile pairs effortlessly with wedding bands or stackable rings, while its shape visually elongates the finger for a graceful effect. The setting’s subtle height also makes it glove-friendly and practical for everyday life.

Should you need a custom fit, resizing is available with care to maintain the ring’s seamless silhouette.
