Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, poised to become the heart of a three-stone engagement ring that balances modern clarity with quiet strength.

This semi-set foundation is crafted from warm 10K rose gold, its subtle blush complementing the cushion’s rounded corners and delicate facets. The band’s clean lines and low-profile setting ensure everyday comfort, while the three-stone arrangement offers a structured yet refined silhouette. Each piece is meticulously hand-finished in our Williamsburg studio, inspected for smooth edges and perfect symmetry.

Choosing a lab-grown cushion diamond means embracing a sustainable approach without compromise on brilliance or purity.

Designed for those who appreciate minimalist geometry with emotional depth, this ring sits comfortably alongside stacking bands or alone as a statement of intentional elegance. Its modest profile fits easily under gloves or sleeves, making it a seamless companion for daily life.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
