One can imagine Marie Antoinette’s indignation when she discovered the latest accusation being made against her in 1785.

Yes, she and the king lived an excessively extravagant lifestyle. Yes, she would admit to being obsessed with fashion, ordering nearly one dress for each day of the year and setting the standard for outrageous poufs—a towering hairstyle that often weaved social or political commentary into its tresses. And, sure, she spent money like it was going out of style, which arguably it was given the serious recession and economic hardship that was causing the rest of France to turn on the nobility.

But she had nothing to do with the massive diamond necklace—647 diamonds clocking in at a breathtaking 28,000 carats—that had gone missing and that she was being accused of having bought but never paid for.
