Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a square diamond, casting a quiet geometry of light across your hand. This semi-set solitaire frame in 14K rose gold offers a warm embrace to a 9 x 9 mm square center stone, inviting you to choose a gem that reflects your story.

Crafted in Williamsburg, the band’s smooth, polished surface balances subtle warmth with a modern silhouette. The low-profile setting ensures the ring sits comfortably beneath daily gestures, while the secure prongs cradle the stone with precision. Each piece is meticulously finished and inspected in-studio, reflecting a commitment to refined craftsmanship.

Our lab-grown diamonds bring clarity and brilliance without compromise, aligning with a sustainable approach to fine jewelry.

Designed for those who appreciate architectural elegance with a romantic edge, this solitaire suits hands that favor bold yet understated statements. Its clean lines pair effortlessly with stacking bands or stand alone as a singular expression of intent.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
