Who shall tell the true story of the diamond necklace? It will probably never be told. The papers of the Cardinal de Rohan, which might have thrown much light upon the subject, were unfortunately destroyed. Little did Marie Antoinette think, as she entered Strasburg in triumph on her marriage journey, that she would encounter, in the magnificent robes of a cardinal’s coadjutor, a man who was to prove her deadly foe,—the insolent and profligate Prince Louis de Rohan. He had been ambassador at Vienna, where he had disgusted Maria Theresa by his profligacy and arrogance. She had procured his withdrawal. He had not been allowed to appear at the court of Versailles; and now for ten long years he had fretted and fumed under a sense of the royal displeasure. Boehmer, the crown jeweller, had, for a period of years, been collecting and assorting the stones which should form an incomparable necklace, in row upon row, pendants and tassels of lustrous diamonds, till the price had reached the royal pitch of three hundred and fifty thousand dollars. This costly “collar” he offered to the king, who would willingly have bought it for the queen had she desired it; but Marie Antoinette replied, that if the money were to be spent, it had better be used in fitting a frigate for the royal navy. His Most Christian Majesty concurred exactly in this sentiment, and, returning the necklace to Boehmer with the words, “We have more need of ships than of diamonds,” thought no more about the matter. Not so did the Cardinal de Rohan, and the _intrigante_ Madame de Lamotte. They had made up their minds to possess the three hundred and fifty thousand dollars represented by the glittering gems. So they laid their clever heads together, and, by forging notes of the queen and sundry other little plots which were wonderfully successful, obtained the necklace, leaving Boehmer to look to the queen for payment. Of course payment was not forthcoming, and in his distress the jeweller related the affair to Madame Campan, telling her he feared he had been duped. Madame Campan proceeded at once to Versailles, and laid the matter before the queen. It was the 15th of August, 1784, Assumption day, and Prince Louis de Rohan, in full pontificals, and wearing the Grand Cross of St. Louis, arrived at Versailles to perform mass in the royal chapel; but he had scarcely entered the _Œil de Bœuf_, when he was summoned to the cabinet of the king. As he entered, Louis XVI. turned upon him suddenly, inquiring, “You have purchased diamonds of Boehmer?” “Yes, sire,” was the trembling reply. “What have you done with them?” the king added. “I thought,” replied the cardinal, “that they had been delivered to the queen.” “Who commissioned you to make this purchase?” “The Comtesse de Lamotte,” was the reply; “she handed me a letter from her Majesty, requesting me to obtain the necklace for her. Indeed, I thought I was obeying her Majesty’s wishes by taking this business upon myself.”
