Used wedding rings?

Monica • One happy mamma! 😍 💙👶🏼
I know I already asked this question but feel like I didn't explain enough. My SO mother passed away 2 years ago and her husband told my SO he could have her ring from her last marriage that ended in divorce. And her other ring cuz he been with his girl for years. We both feel it's bad luck but I was just sitting here thinking, would it really be bad luck? I mean she kept it for so many years after the divorce I'm guessing for one of her sons to use one day.. What do you all think?
