This is wonderful! The heavy gold plated medallion is almost 3 inches and it is heavy. There are no makers marks. I have added in a pair of Coro earrings that came with this necklace. They are a good match. Now this whole centerpiece is 6 inches with the plastic amber beads. The chain is 25 inches. What a piece! This is bold and bright and probably from the late 1960's or early 1970's.
