A continuous sweep of seven round brilliant moissanite stones defines the profile of this silver ring. The curved layout follows the natural shape of the finger, creating an uninterrupted line across the top of the band.
Set in polished 925 sterling silver, the prong structure secures each stone while leaving the sides open to catch the light. It offers a clean, modern take on the classic promise ring silhouette.
