Not saying it applies to Jasmin of course........but quite a lot of completely unattached girls in Uk and Europe wear either an 'engagement' or 'wedding' ring on that finger to hopefully head off some of the inevitable unwanted pesterers, especially when on girls nights out on the town when they are not even thinking about finding male company and want to be left in peace to enjoy themselves.
I'm afraid that the art of wearing an engagement ring or wedding band to ward off unwanted pursuers is not limited to the UK and Europe.
