 FAIR: When Rose is considering jumping off the ship at the beginning  of the movie, she is not wearing the necklace she had on at dinner.  Her hair is also different. In fact, there was a scene that was cut  from the movie where Rose runs back to the parlor suite, tears off  her necklace, lets her hair down, and in a fit of rage, destroys  some of the items in her bedroom before running to the stern to  attempt suicide.
