Lab-Grown Diamond Engagement Ring

Soft light filters through the gentle curves of a 6 x 6 mm cushion diamond, its rounded corners and delicate facets inviting a quiet intimacy. This three-stone semi-set ring in 10K rose gold offers a warm embrace, the blush-hued band cradling your choice of center stone with subtle elegance.

Crafted in Williamsburg, Brooklyn, the band’s slender profile and low-set prongs ensure everyday comfort without sacrificing sparkle. Each piece is meticulously finished by hand, polished to a satin sheen that catches the light with a soft glow rather than glare.

Our commitment to sustainability is reflected in the lab-grown diamond option, providing clarity and brilliance with a lighter environmental footprint. The rose gold’s gentle warmth complements the cushion’s vintage-inspired shape, making this ring a natural fit for those who appreciate romantic details with modern wearability.

Designed to sit gracefully alongside wedding bands or stackable rings, its comfort fit and modest height make it glove-friendly and suited for daily life. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
