What to know some information about a ring

[Muntazrr]

Salam Alaikum Everyone

I found a yakoot ring in garbage. It was just sitting there so i took it and checked it and it turned out to be real silver and real yakoot.

Now i don't know if somebody threw it knowingly or accidentally or if it's someone's who's dead.

So

i want to know that can i wear it?

Do i have to do something before wearing it like put some sadqa in the previous owner's name?

Or something else

Please kindly enlighten me about this situation because I really like this ring.

Also some evidence about your sayings would be nice instead of opinions. ( Sorry if this sentence sounds aggressive.)

Thank you
