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 the centerpiece of your story. This semi-set engagement ring foundation in warm 10K yellow gold offers a modern-minimal silhouette, designed with subtle accent settings that frame the center stone without distraction.
Crafted in our Williamsburg studio, the band is carefully shaped for a comfortable fit that rests low on the finger, allowing daily wear without catching. The polished finish highlights the clarity of the yellow gold, while the accent settings add structured detail that balances refinement with quiet confidence.
Each ring foundation is made to accommodate a lab-grown cushion diamond, reflecting our commitment to ethical jewelry that honors both beauty and sustainability. The choice of a semi-set allows you to select a center stone that perfectly matches your vision, ensuring a truly personalized expression.
Its low-profile design suits hands that favor understated elegance and pairs effortlessly with stacking bands or wedding rings. The smooth shank and secure setting style make it glove-friendly and ideal for everyday life.
