The Heart of the Ocean is a diamond and sapphire pendant in the shape of a heart that was worn by Rose DeWitt Bukater (Kate Winslet) in Titanic, given to her by her fiancée Caledon Hockley (Billy Zane) and gracing her neck on the famous portrait that was drawn on the night the ship fatally hits an iceberg. The design of the necklace was inspired by one of the most precious jewels in history, the Hope Diamond, that was previously owned by King Louis XVI of France. Although the necklace used in the film is not an actual diamond, a real Heart of the Ocean was made following the success of the film. This 170-karat Ceylon sapphire is enclosed by 103 diamonds and was worn by actress Gloria Stuart (the older Rose) at the 1997 Oscars, making it one of the most expensive jewellery pieces ever worn at an award show.
Although the story about the necklace in the film is fictional, rumour has it that there was actually a diamond and sapphire necklace on board of the Titanic back in 1912. Shop owner Henry Samuel Morley had given the necklace to his assistant from Worcester, 20-year old Kate Florence Phillips, who he had left his wife for and had wanted to embark on a new life with in America. Mr Morley didn’t survive the fatal night, but Philips made it off the ship, allegedly with nothing else but her purse and the necklace.
