Lab-Grown Diamond Engagement Ring

Sunlight catches the 8.8 mm round lab-grown diamond at the heart of this platinum ring, scattering light with a familiar brilliance that feels both intimate and enduring. The low-profile setting secures the stone close to the finger, designed to slip comfortably beneath a sleeve or glove without catching.

Crafted in Williamsburg, Brooklyn, the ring’s platinum band is polished to a mirror finish, its weight balanced for daily wear. Accents subtly enhance the center stone’s fire without overwhelming its clarity, each detail inspected by hand to ensure precision and durability.

Choosing a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional visual purity. The round cut’s classic sparkle suits a wide range of hand shapes, offering a versatile silhouette that pairs effortlessly with stacking bands or stands alone.

Resizing is straightforward, handled in-studio with care to preserve the ring’s integrity. Whether designed in person or through our online process, this engagement ring embodies a thoughtful approach to modern romance.
