The Hope Diamond curse story is more a morality fable about the cardinal sin of greed since nearly everyone has something bad or tragic happen to him or her.
According to the legend, the diamond sparkled in the brow of an Indian temple until it was plucked out by a thief, whose punishment for this act was a slow and agonizing death. It was believed that only a person with a pure heart could escape the same fate. In this case, a “pure heart” meant someone who did not try to sell the gem but instead gave it away. Thus the curse ended when Harry Winston donated the Hope Diamond to the Natural Museum of Natural History.
