Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 6.5 mm round diamond, poised to sparkle between two smaller companions—each facet alive with quiet fire. This three-stone semi-set ring invites your choice of center stone, resting in a 10K white gold band shaped by hand in our Williamsburg studio.

The band’s smooth, low-profile silhouette balances presence with everyday ease, its polished finish revealing subtle artisan marks beneath the gleam. Crafted for comfort and durability, the setting secures stones with slender prongs that allow light to dance freely, enhancing brilliance without bulk.

Each diamond you select is lab-grown, offering clarity and sparkle with a lighter environmental footprint, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

Designed for those who appreciate understated elegance, this ring fits comfortably beneath gloves and pairs effortlessly with stacking bands or a wedding ring. Its classic round shape complements a variety of hand sizes, elongating fingers with a familiar brilliance.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a seamless fit, with typical lead times tailored to your custom design journey.
