925 Sterling silver chain and pendant with cubic zirconia

vintage sterling silver pendant with cubic zirconia stones, and a sterling silver snake chain that measures about 17" stamped Italy. both pieces have sterling marks. the mark on the pendant is hard to see it is right behind the large stone on the back. Note: the chain has a small kink in it that I pointed to in the last photo. Also this item is extremely tarnished and I just don't have time to mess with it. It's old, probably from the 80's or earlier. I've had it forever that's why it's so tarnished. sorry I'm too lazy to clean it. 🤣
