Vintage Copper Leaf Necklace Adjustable Length

This lovely vintage copper necklace would be a great addition to any autumn outfit. The chain and clasp offer versality in the length. The measurement from chain end-to-end is 15 3/4", plus the ball and hook. Likely a Pcraft piece. It has some tarnish/discoloration on the back. See last picture. Even prettier in person. Questions welcome. From a smoke free home.
