Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a graceful, tapered brilliance. This three-stone semi-set ring frames a 6 x 3.5 mm marquise center, designed to balance architectural elegance with a soft, modern touch.

Crafted in 14K white gold, the mounting is shaped and finished in our Williamsburg studio, where each prong and curve is refined for a secure yet delicate hold. The low-profile setting ensures everyday comfort, while the smooth band invites stacking or solo wear with ease.

Our lab-grown diamonds offer a clarity and sparkle that honors both beauty and sustainability, reflecting a commitment to ethical jewelry without compromise.

The ring’s dimensions and slender profile suit hands that appreciate refined geometry and a statement that remains wearable daily. Its semi-set nature allows you to select a center stone that resonates personally, making the design uniquely yours.

Should you need resizing or prefer a custom finish, our Brooklyn studio welcomes you to explore options with no pressure and expert guidance.
