2. Heart of the Ocean Necklace
The Heart of the Ocean really is a beautiful myth orchestrated by the amazing James Cameron, but there is a bit of a historical basis there. There was a rare diamond and sapphire necklace on board the Titanic when it sank, but the story behind it is not as elaborate as the one behind Rose’s heart. It is also worth noting that James Cameron did not construct this beauty all by himself! It featured in one of the earlier Titanic films too.
