Lab-Grown Diamond Engagement Ring

Imagine the quiet confidence of a square diamond poised to catch the light with architectural precision. This semi-set halo mounting in 18K white gold awaits a 7.5 x 7.5 mm square center stone, designed to showcase its sharp geometry within a delicate frame.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort without sacrificing brilliance. The halo enhances the center’s presence while maintaining a sleek silhouette, ideal for stacking or wearing solo. Each piece is meticulously finished in our Williamsburg studio, ensuring smooth edges and a comfort fit that feels as natural as it looks.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, offering clarity and sparkle with a lighter environmental footprint.

This mounting suits those who appreciate modern geometry and a refined, practical design—especially hands that favor a subtle yet striking statement. Its low profile makes it glove-friendly and perfect for daily wear.

Should you need resizing or customization, our Brooklyn studio offers personalized consultations to ensure a flawless fit and finish.
