You may be thinking of your grandmother's heirloom engagement ring, but rings aren't the only popular heirloom jewelry items. Cameos, hairpins, hatpins, brooches, pearl necklaces, earrings and cufflinks -- well, the list goes on and on. If it's a shiny trinket, someone will want it even if it's just to take it apart and put it in a new setting. Jewelry is valuable, but it also comes in contact with the body, so there's an almost intimate connection with another person. If that person is dear to you, the object has enormous value apart from its monetary worth.
