Always check the freezer. Several years ago my mother lost the diamond out of her engagment ring again ( 50 years I guess it's possible) She looked for over a year and thought it gone. One Sunday after church they had company come. Grabbing a bag of vegetablesthey had frozen from their garden done the year prior,she poured them in a corning ware dish and microwaved it. Imagine the surprise of the guest who's plate in tinked on.
