Lab-Grown Diamond Engagement Ring

Sunlight catches the broad facets of a 12 x 10 mm emerald-cut diamond, casting a glassy, architectural glow that feels both bold and refined. This semi-set halo engagement ring invites you to select a center stone that will rest within a meticulously crafted 10K white gold frame, where delicate pavé diamonds trace a luminous border.

Each band is shaped and polished in our Williamsburg studio, ensuring a low-profile silhouette that sits comfortably for daily wear without sacrificing presence. The halo setting enhances the emerald’s elongated elegance, while the smooth shank offers a subtle comfort fit, ideal for stacking or solo wear.

Our commitment to lab-grown diamonds means your chosen stone carries clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

Designed for those who appreciate architectural lines and understated luxury, this ring suits hands that welcome a statement piece with clean geometry and refined craftsmanship. The semi-set design allows you to personalize the centerpiece, making it uniquely yours.

Should you need resizing or guidance on selecting the perfect emerald-cut diamond, our Brooklyn studio team is ready to assist with care and expertise.
