Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This semi-set engagement ring frame is crafted from warm 18K yellow gold, designed to cradle a 10 x 5 mm marquise center stone with precision and grace.

The band’s low-profile setting ensures the diamond sits close to the hand, reducing snagging and enhancing everyday comfort. Smooth edges and a balanced weight create a secure yet effortless wear, ideal for those who value both form and function. Accents along the shank add a refined touch without overwhelming the stone’s architectural shape.

Each piece is finished in our Williamsburg studio, where expert hands polish and inspect every detail to meet exacting standards. The choice of lab-grown diamonds reflects a commitment to ethical jewelry, offering clarity and brilliance with a smaller environmental footprint.

This ring suits someone who appreciates a sleek silhouette that complements slender or average finger shapes, and its modest height makes it glove-friendly and stackable with other bands. The semi-set design invites you to select a center stone that resonates personally, allowing for a truly bespoke expression.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care recommendations to maintain the ring’s subtle sheen over time.
