Lab-Grown Diamond Engagement Ring

Sunlight catches the 7.4 mm round diamond, scattering light like a quiet Brooklyn morning through a Williamsburg loft window. This solitaire ring, set in warm 14K yellow gold, balances artisanal craftsmanship with everyday elegance.

Each band is hand-shaped and polished in our Williamsburg studio, its smooth comfort fit designed to sit low on the finger without sacrificing brilliance. The classic round cut maximizes fire and sparkle, framed securely by a four-prong setting that showcases the diamond’s lively dance of light.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and beauty without compromise.

Its modest profile and sturdy build make it ideal for daily wear, whether worn solo or paired with a wedding band. The ring’s balanced weight and rounded edges ensure it feels natural on the hand, complementing a range of finger shapes and sizes.

Should you need a custom fit, resizing is available with care to maintain the ring’s seamless finish and structural integrity.
