The Hope diamond is one of the largest blue diamonds known. Discovered in India, the original 115-carat stone was sold to King Louis XIV in the 1660s and remained part of the French crown jewels until a theft in 1792. In 1830, London banker Thomas Hope purchased a 45.5-carat diamond, now believed to have been cut from the stolen French jewel. After changing hands many times, the Hope diamond was eventually donated to the Smithsonian by jeweler Harry Winston. Why do some think the gem is cursed? Discuss
