|The Hope Diamond. The Hope is believed to be cursed. Evalyn Walsh McLean, one of its former owners, referred to the rock as her "lucky charm." Soon after acquiring it, though, McLean's son died in a car accident, her husband divorced her and died insane, and her daughter committed suicide. She herself became a morphine addict. In 1959, the 45.52-carat rock was donated to the Smithsonian. It was sent by regular mail.|
La Peregrina Pearl. - After passing from the hands of Spanish, French, and English kings and queens (Bloody Mary included), the pearl eventually wound up perched on the bosom of an American royal, Elizabeth Taylor, in 1969. Richard Burton purchased the pearl for her, outbidding a prince. Taylor then misplaced La Peregrina in a Las Vegas hotel, only to find it in her dog's mouth.
