Lab-Grown Diamond Engagement Ring

Soft light filters through a cushion-cut diamond’s gentle curves, catching the eye with a quiet, vintage-inspired glow. This semi-set three-stone engagement ring foundation in platinum awaits your choice of a 6 x 6 mm center stone, designed to cradle each gem with delicate precision.

Crafted in Williamsburg, the platinum band offers a cool, substantial feel that balances strength with refined elegance. The three-stone setting is low-profile, allowing the ring to sit comfortably beneath gloves or alongside other bands without catching. Each prong is hand-finished to ensure security and subtle sparkle, reflecting the studio’s commitment to meticulous craftsmanship.

Our lab-grown diamonds bring clarity and brilliance with a lighter environmental footprint, aligning with a modern ethos of ethical jewelry. This setting suits those who appreciate romantic detail and daily wearability, especially for hands that favor a graceful, understated silhouette.

Should you wish to adjust sizing, our in-studio experts handle resizing with care to maintain the ring’s integrity and finish. Typical lead times allow for thoughtful customization without rush.
