Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 6.5 mm round diamond, poised to become the centerpiece of a three-stone story. This semi-set engagement ring foundation, crafted from warm 14K yellow gold, invites your choice of lab-grown stones to complete its artisan-crafted embrace.

Each band is hand-shaped in our Williamsburg studio, its smooth surface polished to a soft glow that complements the classic round cut’s lively sparkle. The three-stone setting balances presence with wearability, designed low enough for daily comfort yet elevated to showcase the interplay of light between the center and side stones.

Our commitment to sustainability is reflected in the lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint. The warm yellow gold band, finished with subtle hand-rubbed details, feels substantial yet comfortable, fitting naturally alongside other stackable rings or worn solo.

Ideal for those who appreciate a blend of tradition and modern ethics, this semi-set ring adapts to your personal vision while maintaining a refined silhouette that slips easily under gloves or sleeves. Resizing is available to ensure a perfect fit, crafted with care in Brooklyn’s artisan community.
