The Heart of the Ocean is the name of a fictional blue diamond featured prominently in the 1997 film Titanic. 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 Hockley, played by Billy Zane, a week before he sailed on the ill-fated ocean liner Titanic. The necklace was meant to be given as an engagement present to his fiancée Rose, played by Kate Winslet and Gloria Stuart. It is believed that both Rose and the necklace went down with the ship, leading some of the main characters to believe the necklace lies somewhere within the wreckage of the Titanic.
