Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the hand with subtle drama. This solitaire semi-set ring in 18K white gold offers a refined foundation for a 9 x 4.5 mm center stone, designed to showcase the gem’s distinctive shape without distraction.

Crafted with a low-profile setting, the mounting ensures the diamond sits close to the finger, balancing presence with everyday comfort. The polished white gold band is smooth beneath the hand, engineered for durability and ease of wear, whether alone or paired with stacking bands.

Each piece begins in our Williamsburg studio, where precision meets quiet craftsmanship. The semi-set design invites you to select a lab-grown diamond of exceptional clarity and brilliance, reflecting our commitment to ethical jewelry that honors both beauty and sustainability.

Ideal for those who appreciate architectural elegance and a sleek silhouette, this ring suits slender to medium finger sizes and slips easily under gloves or sleeves. Its streamlined profile makes it a practical choice for daily wear without sacrificing style.
