The sale in Geneva is one of the most important royal jewellery auctions ever, says Sotheby’s.
Marie Antoinette was an Austrian princess before her marriage to France’s King Louis XVI. Her extravagant lifestyle turned her into a hate figure in the years leading up to the French Revolution, when many French people could barely afford to feed their families.
She smuggled out her jewellery to her family in Austria before her failed attempt to flee France with Louis XVI and their children. She was guillotined in 1793 at the age of 37.
