Vintage Modernistic Norway Sterling Abstract Ring

Here's a great vintage Scandinavian design ring...abstract and modernistic...very unique! Inside is marked 925-S NORWAY and then on the outside band, there are 2 tiny hallmarks that indicate 3 crowns and the letter ~S~ which stands for Sweden. The ring has an adjustable band which is brilliantly designed to look like a solid band. Top measures 7/8 inch wide. Ring is in excellent condition.
