Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with a subtle, elegant drama. This semi-set halo ring foundation in 10K white gold awaits a 6 x 3 mm marquise center, designed to amplify the stone’s signature brilliance through a delicate frame of smaller diamonds.

Crafted in our Williamsburg studio, the band is shaped for comfort with a low-profile setting that sits close to the hand, making it ideal for daily wear. The artisan finish reveals meticulous hand polishing and precise prong work, ensuring the halo enhances light play without adding bulk.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, offering clarity and sparkle without compromise.

The slim band and modest height suit slender to medium finger sizes, while the halo setting adds visual width—perfect for those seeking a balance between boldness and refinement. Its design also pairs effortlessly with stacking bands or a wedding band.

Should you need resizing, our in-studio experts handle adjustments with care to maintain structural integrity and finish.
