Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 10 x 10 mm cushion-cut diamond catching the light with a gentle, vintage-inspired shimmer—ready to become the heart of your engagement story. This semi-set solitaire ring foundation, crafted from warm 18K rose gold, offers a subtle contrast against the cool sheen of white gold, creating a harmonious balance without overwhelming the stone.

Expertly designed for everyday wear, the low-profile setting keeps the center stone close to the finger, reducing snagging while maintaining a refined silhouette. The band’s smooth finish and comfort fit ensure it sits naturally, whether worn alone or paired with a wedding band. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet craftsmanship.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds—offering clarity and brilliance with a significantly reduced environmental footprint.

This solitaire mounting suits those who appreciate a blend of classic form and modern practicality, especially for hands that favor understated elegance and a secure fit. The semi-set design invites you to select a cushion-cut diamond that resonates with your personal vision.
