Lab-Grown Diamond Engagement Ring

When light catches the sharp edges of a 5.5 x 5.5 mm square diamond, it reveals a quiet geometry that balances strength with subtle brilliance. This semi-set halo engagement ring in 10K white gold offers a low-profile silhouette designed to sit close to the finger, minimizing snagging while maximizing daily comfort.

Crafted in Williamsburg, the band is meticulously finished with a smooth comfort fit, ensuring it feels as natural as it looks. The halo setting frames the square center stone with precision, enhancing its architectural clarity without overwhelming the design. Each piece undergoes careful inspection to meet exacting standards of polish and symmetry.

Choosing a lab-grown diamond means embracing a cleaner origin story—ethical jewelry that reduces environmental impact without compromising on visual purity.

Its streamlined profile suits hands that favor understated elegance and works well for stacking with complementary bands. The square shape’s crisp lines lend a modern edge, especially flattering on slender fingers or those seeking a geometric statement.

Resizing is available to ensure a tailored fit, with typical lead times reflecting our handcrafted approach in Brooklyn.
