Question: was the hope diamond ever on the titanic

Answer: No, 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.
