A diamond pendant with a natural pearl, once in the collection of Marie Antoinette. The pearl, along with many other jewels, was sent by Marie Antoinette to Austria in 1791. The pieces made their way into the hands of her daughter when she was living in Vienna; the duchesse d'Angouleme later bequeathed them to others in her will. These pieces will go up for auction on November 12, 2018, from Sotheby's.
