A stunning ring designed by Uni David-Andersen for her own studio in Norway. The ring was part of the studio's "Troll Series" of 1964 and was titled "Uni's Promise". Pieces from the collection featured silver designs which made use of local stones found in Norway. Emphasizing the simplistic beauty of natural materials, this was a new direction for jewelry at the time. With its clean lines and dramatic height, it's an exemplary piece. The stone is a deep color which is amber-hued in the light. It is in beautiful condition and comes with the original box.
