Lab-Grown Diamond Engagement Ring

Sunlight catches the edges of a 12mm round diamond, its facets radiating a steady, confident brilliance that anchors a modern five-stone design. This semi-set platinum band awaits your choice of center stone, crafted with a low-profile setting that balances presence with everyday ease.

Each platinum shank is hand-finished in Williamsburg, polished to a satiny smoothness that feels weighty yet comfortable on the finger. The five-stone arrangement offers architectural clarity, the side stones framing the center with precise symmetry and subtle sparkle.

Our lab-grown diamonds provide the same optical purity as mined stones, with a fraction of the environmental impact—an ethical choice made without compromise.

Designed for those who appreciate structured minimalism, this ring suits hands that favor clean lines and a confident silhouette. Its low profile and comfort fit make it ideal for stacking or daily wear, slipping easily beneath gloves or sleeves.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without disrupting the ring’s balance. Typical lead times reflect the custom nature of the semi-set design.
