Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise, its tapered points drawing the eye along a graceful arc of brilliance. This semi-set three-stone engagement ring in polished platinum awaits your choice of an 8 x 4 mm lab-grown diamond, ready to become a personal emblem of connection.

Crafted with a low-profile setting, the band’s smooth comfort fit ensures it rests gently against the skin, ideal for daily wear and effortless stacking. Each prong is meticulously finished by hand in our Williamsburg studio, balancing secure hold with delicate elegance.

Our lab-grown diamonds offer a clarity and sparkle indistinguishable from mined stones, created with a commitment to sustainability and ethical sourcing that quietly honors the earth.

The marquise shape’s elongated form naturally complements slender fingers, while the three-stone design adds depth and narrative—perfect for those who appreciate subtle symbolism and refined craftsmanship.

Should you need resizing, our in-house artisans provide precise adjustments to ensure a seamless fit without compromising the ring’s integrity.
