I have had my shared-prong eternity band for about 3 years, and some of the stones are starting to come a little loose. That is to say, there is some movement (generally turning) of some stones within their individual settings. I am wondering (1) whether others have had this problem and (2) if so, do I really need to do anything about it? This was a handcrafted, commissioned piece and I'm no longer in contact with the jeweler, so I can't go back and ask for HIM to tighten the settings; rather, I'd have to go to another jeweler and pay for it to be done. I don't really care enough to do that unless there's some reason I need to (for instance, if movement within the setting is a precursor to stones just falling out willy-nilly later on...).
