I have a solitaire engagement ring and an eternity wedding band and this is the second time in two years that a diamond has become loose on my band. I know that the setting for the eternity band isn't the most stabe (it's a shared claw setting with diamonds that are .20 carat each) but it seems the main cause is my engagement ring rubbing up against my wedding band. Besides wearing the rings on two separate fingers (i.e. my engagement ring on my right hand) does any one have a suggestion on how to avoid this problem? Any advice would be appreciated!
