With this money, Jeanne was able to make her way into respectable society.
Because she openly boasted about her mythical relationship with the Queen, many assumed the affair was genuine.
He claimed to have the Queen's authorization for the purchase and showed the jewelers the conditions of the bargain in the Queen's handwriting.
Rohan took the necklace to Jeanne's house, where a man, whom Rohan believed to be a valet of the Queen, came to fetch it.
Rohan offered d'Oliva a rose, and, in her role as the Queen, she promised him that she would forget their past disagreements.
Jeanne de la Motte took advantage of the Cardinal's belief in her by borrowing large sums of money from him, telling him that they were for the Queen's charity work.The diamond necklace was commissioned by Louis XV of France for his mistress, Madame du Barry.At the death of the King, the necklace was unpaid for, almost bankrupting the jewellers and leading to various unsuccessful schemes to secure a sale to Queen Marie Antoinette.According to others, Louis XVI himself changed his mind.After having vainly tried to place the necklace outside France, the jewellers again attempted to sell it to Marie Antoinette after the birth of Louis Joseph, Dauphin of France, in 1781. A confidence trickster who called herself Jeanne de Valois-Saint-Rémy, also known as Jeanne de la Motte, conceived a plan to use the necklace to gain wealth and possibly power and royal patronage.A descendant of an illegitimate son of Henry II of France, Jeanne had married an officer of the gendarmes, Nicholas de la Motte, the soi-disant "comte de la Motte", and was living on a small pension granted to her by the King.In March 1785, Jeanne became the mistress of the Cardinal de Rohan, a former French ambassador to the court of Vienna.At this time, the Cardinal was trying to regain the Queen's favour to become one of the King's ministers.Jeanne de la Motte, having entered court by means of a lover named Rétaux de Villette, persuaded Rohan that she had been received by the Queen and enjoyed her favour.On hearing of this, Rohan resolved to use Jeanne to regain the Queen's goodwill.Jeanne assured the Cardinal that she was making efforts on his behalf.
