Lab-Grown Diamond Engagement Ring

Morning light catches the subtle sparkle of a 4.8 mm round diamond, poised to become the heart of your story. This semi-set three-stone ring foundation in 10K white gold offers a sleek, modern-minimal silhouette defined by clean lines and structural clarity.

Crafted in Williamsburg, the band’s low-profile setting balances refined geometry with everyday comfort, its smooth finish inviting wear from dawn to dusk. The three-stone arrangement frames your chosen center stone with quiet confidence, allowing light to dance freely across each facet.

Each piece begins with a responsibly sourced lab-grown diamond, reflecting a commitment to ethical jewelry that honors both beauty and sustainability. The 10K white gold is polished to a soft sheen, designed for durability without excess weight.

Ideal for those who appreciate architectural simplicity and a ring that layers effortlessly with other bands, this mounting suits a variety of hand shapes and sizes, offering a glove-friendly fit that never feels bulky.

Should you need resizing or custom adjustments, our Brooklyn studio ensures precise craftsmanship with attentive care and reasonable lead times.
