The Affair of the Diamond Necklace - Marie Antoinette

Marie Antoinette is famous for saying "Let them eat cake" (which she may or may not have said) but her bad reputation with the people of France went fairly deep. To the point she was blamed for an intricate heist to steal a diamond necklace... that she didn't actually ever want. That diamond necklace by the way? Worth 14 million dollars. Yeah. That's a lot of cake.
