Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 9 mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set design invites your choice of center stone, framed by two delicate side settings crafted in warm 14K yellow gold.

Each band is shaped and polished in our Williamsburg studio, where the artisan’s hand ensures a smooth comfort fit that rests lightly against the skin. The three-stone setting balances presence with wearability, its low-profile silhouette designed for everyday grace without catching or snagging.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both beauty and sustainability. This ethical approach reduces environmental impact while delivering exceptional sparkle.

The ring’s gentle curves and classic round shape suit a variety of hand sizes, especially those who appreciate a design that layers well with wedding bands or stackable rings. Its subtle height makes it glove-friendly and ideal for daily wear.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s seamless finish. Typical lead times are communicated clearly during your consultation.
