I want to have an implanted "ring" when I get married

I want me and whoever my SO might be to get cool tattoos around our ring fingers and then at the very top where the stone would be, I would get an implant mount (its like a threaded titanium hole permanently buried in your skin... basically haha) and then get custom made stones to exchange with eachother. Now when I find a girl who is down for that, I know she's a keeper
