Lab-Grown Diamond Engagement Ring

Sunlight catches the halo’s delicate circle, scattering light around a 12mm round center that promises quiet brilliance. This semi-set engagement ring invites your choice of a lab-grown diamond, ready to become the heart of a design crafted for everyday grace.

Forged in 10K white gold, the band is shaped with a low-profile halo setting that balances presence with subtlety, ensuring comfort beneath gloves or alongside a stack. Each curve is polished in-studio, inspected for smooth edges and a seamless fit that suits daily wear without fuss.

Our commitment to ethical jewelry shines through the lab-grown diamond option, offering clarity and sparkle with a smaller environmental footprint. The round cut’s classic fire and scintillation complement a wide range of hand shapes, elongating fingers with its balanced symmetry.

Designed for those who appreciate refined engineering and understated elegance, this ring’s halo setting enhances the center stone’s size while maintaining a sleek silhouette. Resizing is available to ensure a perfect fit, crafted with care in Williamsburg’s studio.
