Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set solitaire ring invites you to select a center stone that will become the centerpiece of a modern-minimal design.

Crafted in a fixed two-tone blend of 18k white and 18k white and platinum and 18k white and platinum, the band balances cool sophistication with structural clarity. The six-prong setting secures the diamond with architectural precision, allowing light to enter freely while maintaining a lightweight, comfortable fit for daily wear.

Each ring is finished by hand in our Williamsburg studio, where expert polish and inspection ensure a smooth profile that slips easily beneath gloves or alongside stackable bands. The low-profile mounting keeps the silhouette sleek without sacrificing presence.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, offering a sustainable choice with the same brilliance and clarity as mined stones.

Designed for those who appreciate confident understatement, this solitaire suits hands that favor elongated shapes and a refined, modern aesthetic. The semi-set format means your chosen oval diamond—up to 12 by 10 millimeters—will harmonize perfectly with the ring’s clean lines.

Resizing is available to ensure a precise fit, and our team is happy to guide you through care and customization options.
