Lab-Grown Diamond Engagement Ring

Sunlight filters through the elongated facets of an 11 by 9 mm emerald cut diamond, casting a glassy, architectural glow that draws the eye along its clean lines. This five-stone semi-set in platinum offers a refined foundation, inviting your choice of center stone to become the centerpiece of a quietly dramatic story.

Crafted in our Williamsburg studio, the platinum band is polished to a mirror finish, its low-profile setting designed for everyday grace and comfort. The five-stone arrangement balances presence with subtlety, allowing the emerald cut’s clarity and step-cut brilliance to unfold without distraction.

Each lab-grown diamond is selected for its ethical origin and sustainability, reflecting a commitment to responsible craftsmanship without compromise. The cool weight of platinum ensures durability while maintaining a sleek silhouette that pairs effortlessly with stacking bands or a wedding band.

Ideal for those who appreciate architectural elegance and a ring that feels as natural on the hand as it looks. Its semi-set state offers flexibility to personalize with a center stone that suits your vision and lifestyle.

Resizing is available to ensure a perfect fit, and our in-studio consultations in Williamsburg provide a relaxed space to explore your custom design options.
