This bronze necklace was designed by Pentti Sarpaneva and made by Kalevala Koru in the 1970's. The pendant has a green enamel disc at the center. The pendant is 1 1/4 inches in diameter and the chain is about 27 inches long. There is a stamp on the back of the pendants, a bit hard to read, but I think it says "Finland kk". In good condition with some vintage patina. Let me know if you have questions.
