Lot of 5 Marcasite & Crystal Necklaces w/Earrings

I was in a Marcasite phase a few years ago and collected too many! I’ve already sold 10 sets and I have these beauties left! What’s fun about this lot is the earrings can go with any of the necklaces. I do not know if they’re .925 sterling silver, but they do not react to my magnet. Hence, I’m not listing them as such. I’ve kept each piece is separate small plastic bags so they haven’t tarnished. They really are so pretty!
