Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 12 x 12 mm cushion diamond, its gentle glow poised to become a daily companion. This semi-set solitaire ring features an 18K white gold band crafted for subtlety and strength, designed with a low-profile setting that rests close to the finger, minimizing snagging while maximizing comfort.

Each band is hand-finished in our Williamsburg studio, polished to a satiny sheen that complements the diamond’s vintage-inspired facets. The mounting’s clean lines ensure the stone’s glassy, luminous character remains the focal point, while the secure prongs balance technical precision with understated elegance.

Our diamonds are lab-grown, offering a clear, sustainable alternative that aligns with thoughtful craftsmanship and environmental mindfulness.

Ideal for those seeking a solitaire that wears effortlessly every day, this ring’s comfort fit and modest height make it glove-friendly and stackable with other bands. The cushion shape’s soft geometry flatters a range of hand sizes, adding a quiet architectural grace without overwhelming delicate proportions.
