This is the cutest idea. You can get a locket as a necklace, keychain or bracelet either in a heart or a circle. Just open it up and put in charms of your choice. There are birthstone hearts, little boys or girls with birthstones, pink or yellow ribbons, American flag, I love Grandma, dog foot prints, charms about hobbies, the list goes on. My fav is the tiny little diamond ring. These are so fun to make either for yourself or as a gift.
