Why does this keep appearing in my house?

So for a little context I have a pair of earrings that I hadn't worn in years. One day I found a piece of one of the earrings on the floor in my house. I immediately thought that was strange because I hadn't worn them in so long. So went to investigate. But when I found my earrings they were whole. So I thought it was very strange and threw away the broken piece. Maybe a month or two later this happened again. Again I found the same looking broken piece and inspected my earrings. They were still intact perfect. So I showed my fiancé how weird this was and they agreed and I threw the broken piece away again. This happened at least two more times. During that I got rid of the earrings. But today, I just found that same broken piece yet again! Somehow just back. This is the most bizarre thing, and I am so sick of this thing turning up. It’s been like two years!
