A necklace consisting of 500 diamonds, and worth £80,000, which one Madame de la Motte induced the jeweller who "made" it to part with for Marie Antoinette, on security of Cardinal de Rohan, and which madame made away with, taking it to pieces and disposing of the jewels in London; the swindle was first discovered when the jeweller presented his bill to the queen, who denied all knowledge of the matter; this led to a trial which extended over nine months, gave rise to great scandal, and ended in the punishment of the swindler and her husband, and the disgrace of the unhappy, and it is believed innocent, queen. See Carlyle's "Miscellanies."
