Lab-Grown Diamond Engagement Ring

Imagine the graceful silhouette of a marquise diamond poised to elongate the finger with subtle drama. This semi-set engagement ring in warm 18K rose gold awaits your choice of a 10 x 5 mm center stone, offering a refined balance between presence and everyday ease.

Crafted with a low-profile setting, the band’s gentle curve ensures comfort beneath gloves or alongside stackable favorites. The rose gold’s soft glow complements the marquise’s tapered points, while delicate accent stones frame the center with quiet precision. Each ring is meticulously finished and inspected in our Williamsburg studio to meet exacting standards of fit and finish.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable practices, reflecting a modern approach to ethical jewelry.

Designed for those who value a sleek silhouette and reliable wearability, this ring suits hands seeking elegance without bulk. The semi-set format invites you to select a marquise stone that speaks personally, making the design uniquely yours.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers expert advice with no pressure and transparent timelines.
