Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of an 11 x 11 mm cushion diamond, its gentle glow framed by two smaller stones that balance presence with quiet elegance. This semi-set three-stone ring foundation is crafted from warm 18K rose gold, its subtle blush complementing the diamond’s vintage-inspired silhouette.

Each band is hand-shaped in our Williamsburg studio, polished to a satin finish that feels smooth against the skin. The low-profile setting ensures daily wearability without catching, while the three-stone arrangement offers a harmonious play of light and shadow, emphasizing the cushion’s soft sparkle.

Our diamonds are lab-grown, chosen for their clarity and ethical origin, reflecting a commitment to sustainability without compromise on brilliance.

This ring suits those who appreciate artisan craftsmanship and a design that layers meaning—ideal for hands that favor a comfortable fit and a style that pairs effortlessly with stacking bands or a wedding band.

Should you wish to adjust the fit, resizing is available through our in-studio service, ensuring a seamless experience from design to wear.
