I have an annoyingly small size difference between my right and left 4th fingers, and it looks like I'll need to do some resizing! I got a gorgeous saphhire ring that almost fits on my left hand, but won't go over the right knuckle - and I don't wanna replace my ering. And speaking of which, at certain times of the day/year it's too loose, so I don't know the best solution for that. In the summer I'm sure it will fit snugly, so I don't know if I should resize it but it's really moving around a lot now.
I haven't had a ring resized for years - any pointers on things to watch for, ask for, how to find someone good, etc?
