Lab-Grown Diamond Engagement Ring

Sunlight catches the halo’s delicate circle, scattering light across a hand poised to say yes. This semi-set engagement ring invites your choice of a 12 mm round diamond, known for its brilliant sparkle and classic allure.

Crafted in 18K white gold, the mounting features a low-profile halo setting designed for everyday wear. The band’s subtle curvature and secure prongs ensure comfort and durability without excess height, making it glove-friendly and stackable with ease. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet refinement.

Our commitment to lab-grown diamonds means your ring carries a clear ethical advantage, minimizing environmental impact while maximizing clarity and brilliance.

This design suits those who appreciate a balance of tradition and modern practicality—ideal for hands that value comfort without sacrificing presence. The halo setting enhances the center stone’s size visually, perfect for a 12 mm round diamond’s radiant geometry.
