In the story, the 56 carat diamond was originally owned by Louis XVI and cut into a heart shape after the French Revolution . In the film the necklace was purchased by Pittsburgh steel tycoon Caledon Hockley, played by Billy Zane, a week before he sailed on the ill - fated ocean liner RMS Titanic . The necklace was meant to be given as an engagement present to his fiancée Rose DeWitt Bukater, played by Kate Winslet and Gloria Stuart . It is believed that both Rose and the necklace went down with the sinking of the ship, leading some treasure salvagers to believe the necklace lies somewhere within the wreck of the Titanic . </P> <P> The story of the Hope Diamond bears many similarities to the story of the Heart of the Ocean with the obvious exception of the Hope Diamond not actually having been on board the Titanic . In the 1953 film Titanic, a blue diamond plays an important role in a love affair as well . A primary plot point in this earlier film is the theft of the diamond, which creates a dramatic break in a romantic relationship which is similar to the 1997 film . </P>
