Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a subtle elongation that draws the eye along the finger’s natural line. This solitaire semi-set invites your choice of a 7 x 3.5 mm lab-grown diamond, its distinctive shape offering a refined balance of drama and elegance.

Crafted in 14K yellow or white gold, the mounting features a low-profile setting designed for everyday wear. The secure prongs hold the stone close to the band, minimizing snagging while maintaining a sleek silhouette. Each ring is hand-finished in our Williamsburg studio, ensuring smooth edges and a comfort fit that feels as natural as it looks.

Our diamonds are sustainably grown, reflecting a commitment to ethical jewelry without compromise on brilliance or clarity.

This design suits those who appreciate architectural form with practical wearability—ideal for stacking or wearing solo. The slender band complements the marquise’s elongated shape, flattering a range of hand sizes with understated confidence.

Resizing is available to ensure a precise fit, and the semi-set format allows you to select a center stone that resonates personally.
