bronze kalevala koru bracelet

This is a bronze bracelet with a green patina inlay. It has a hinge on the back and it closes with a unique pin and chain clasp. As soon as saw it behind the counter at a local thrift shop, I knew it was something special. There is a makers mark, a double k in a circle. After researching a little, I found out that it was made by kalavala koru, a jeweler in Helsinki, Finland that was established in 1935. They were a grop of women who were inspired by artifacts from the Kalevala museum and based their jewelry designs off them. They are one of the leading jewelry manufacturers in Finland today. I am unsure of the era this was made in and what its worth.
