Today, the Diamond Necklace affair has been relegated to the status of sensational footnote in history books about the French Revolution. Throughout the 19th century, however, the scandal was widely believed to have been a major factor in the overthrow of the Bourbon monarchy. Decades after the French Revolution, Napoleon observed from the vantage point of his post-Waterloo exile: “The Queen’s death must be dated from the Diamond Necklace trial”. […] And here’s the irony: While the Diamond Necklace affair was the scandal that most tarnished Marie Antoinette’s reputation, it was one in which she was almost certainly guiltless.
The origins of the affair stretched back to Louis XV, who wished to lavish on his mistress, Madame du Barry, a splendid diamond necklace containing 647 stones and weighing 2,800 carats (worth roughly $15 million today). But Louis XV died before the sale of the necklace was concluded. And when young Louis XVI took the throne, the Paris jewelers Boehmer and Bassenge hoped the new king would purchase the same necklace for his own queen, Marie Antoinette. However, she refused to accept a piece of jewelry that had been created for the previous king’s mistress.
Meanwhile, a socially ambitious minor aristocrat named Jeanne de la Motte was plotting to get her hands on the necklace. Married to the Comte de la Motte, she was also the mistress of Cardinal de Rohan, former French ambassador to Marie Antoinette’s native Austria. Madame de la Motte managed to convince Cardinal de Rohan not only that Marie Antoinette wished to possess the necklace, but that she was acting on the Queen’s behalf. He could ingratiate himself at court, she insisted, by obtaining it. Cardinal Rohan foolishly purchased the necklace on credit, under the naive belief that he’d be repaid by Marie Antoinette. The scam concluded with Madame de la Motte stealing the necklace from the cardinal and, using her husband’s louche connections, selling it in pieces through fences in England.
This tawdry business was closer to comic opera than an affair of state. But when the fraud was discovered, the scandal gripped Parisian society. Louis XVI was so infuriated that he had Cardinal de Rohan arrested and imprisoned in the Bastille, which only heightened public interest. Marie Antoinette was already being caricatured in pamphlets as a depraved nymphomaniac. It was now open season.
In some caricatures, she appeared as a wild beast, a tiger feeding on the French nation. In others, she was depicted as an ostrich, a French wordplay with her home country Autriche, for Austria, which reads like autruche for ostrich. Even worse, she was depicted in pornographic postures, legs open and genitals gaping, cuckolding her obese husband with a succession of lovers, including lesbian trysts. Allusions to her sexual appetites suggested a carnal relationship with Satan. Robespierre’s publication Le Journal des hommes libres described her as “more bloodthirsty than Jezebel, more conniving than Agrippina”. The pamphlets blamed Marie Antoinette for all the nation’s misfortunes, including economic recession. She was so hated by the French public that there were serious concerns for her physical safety.
[…]
Cardinal de Rohan, meanwhile, was tried for his role in the Diamond Necklace affair. Astonishingly, he was acquitted. The scheming Madame de la Motte met a different fate. She was found guilty of theft and sentenced to be whipped and branded on the shoulder with the letter V for voleuse (thief). She was also incarcerated in the Salpêtrière prison in Paris, but escaped to London. In 1789, she published a book, Mémoires justificatifs, a scathing tell-all memoir about Marie Antoinette. It was a good year to attack the French monarchy, for the revolution was just getting going. Madame de la Motte was never returned to France to face justice. Exiled in London, she died in 1791 after falling from a window, apparently fleeing debt collectors. She was buried in St. Mary’s Churchyard in south London.
