Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 12 x 12 mm cushion-shaped diamond poised to catch the light with a gentle, vintage-inspired radiance. This solitaire semi-set ring foundation, crafted from warm 18K rose gold, offers a subtle contrast to the cool sheen of 18K white gold, creating a harmonious balance without two-tone complexity.

The band’s low-profile design ensures the setting sits close to the finger, minimizing snagging and enhancing everyday comfort. Expertly finished in our Williamsburg studio, the smooth shank features a comfort fit that molds naturally to the hand, making it ideal for daily wear and effortless stacking.

Each ring is designed to showcase the unique glassy facets of a cushion cut, whose soft corners and gentle sparkle evoke a quiet elegance. Our semi-set approach invites you to select a lab-grown diamond that meets your clarity and color preferences, ensuring a personalized centerpiece with ethical provenance.

Lab-grown diamonds reduce environmental impact while maintaining the brilliance and durability expected from fine jewelry. This ring’s design suits those who appreciate refined craftsmanship and a subtle statement, especially for hands that favor a balanced, comfortable silhouette.
