Rose then throws the necklace off the Keldysh, just above the Titanic. By throwing the necklace into the Atlantic ocean, Rose finally lets go, because she is ready to make peace with Jack and the other Titanic victims; she is finally ready to move on.
In one of the final scenes, a bare footed Rose walks to the railing of the search ship, climbs up on it in similar fashion to when she and Jack were on the prow of the Titanic, and throws it into the ocean.
The Heart of the Ocean was what set the plot of Titanic into motion as it’s Brock Lovett’s (Bill Paxton) expedition to find the necklace what brings Rose into the mix to share her story, and in the end, it’s revealed that Rose had had the necklace all this time, and finally got rid of it by throwing it into the ocean.
After the sinking of the Titanic, Rose went on to live a full and engaging life that saw her keep a promise that she’d made to a man she’d fallen in love with during her youth and had lost during one of the biggest tragedies in her life.
Why did Rose toss the heart of the ocean over the rail?
The overall feeling as to why Rose tossed the Heart of the Ocean over the rail in Titanic is pretty simple: it was time. To better explain that, one has to understand the essence of the story and why she kept it, to begin with, and how it came into her possession.
Early in the film, Cal gives Rose the Heart of the Ocean, he says: “Open your heart to me Rose“. And she covers the diamond with her hand. At the end of the film, old Rose lets the Heart of the Ocean go, having opened her heart to Jack and his memory.
Why did rose throw the diamond in the ocean?
Rose was the owner of the necklace, which was given to her by her then-fiancé Cal Hockley (Billy Zane). Given the rarity of the necklace’s blue diamond, Lovett’s team surely weren’t the only ones looking for it, so throwing it into the ocean ensured that it wouldn’t fall into the wrong hands.
In Titanic, the elderly Rose visits a ship searching for the Heart of the Ocean diamond, set in a necklace. Unbeknownst to them, she actually carries it with her.
Why did Rose Thorne throw her bag over the side?
Now to the best part, the reason why she tossed it over the side. Again, it’s a simple matter, since Rose had told her story, she’d relayed what had happened aboard the Titanic, and she was ready to go, to meet Jack and the rest of those that had been fated to perish upon the ship on that fateful night.
