Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 9mm 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 stones that balance brilliance with subtlety.

Crafted from warm 10K rose gold, the band is shaped in our Williamsburg studio with a low-profile setting that rests comfortably against the finger. Each prong is hand-finished to secure stones while allowing light to dance freely, enhancing the diamond’s natural fire. The smooth interior offers a comfort fit, ideal for daily wear and effortless stacking.

Our diamonds are lab-grown, offering clarity and sparkle with a mindful approach to sustainability—an ethical choice without compromise.

This ring suits those who appreciate artisan craftsmanship and a design that blends classic round brilliance with modern sensibility. Its modest profile pairs well with wedding bands or stackable rings, and the rose gold hue complements a variety of skin tones.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio provides personalized consultations to ensure your ring fits perfectly.
