Napoleon, Joseph Bonaparte, was installed as king of Spain. His rule continued for five years, and when he was forced to leave the kingdom, after the defeat of the French forces at the Battle of Vitoria, he took some of the crown jewels with him, including La Peregrina. At that time, the pearl got its name "La Peregrina - the Wanderer". In his will, Joseph Bonaparte left the pearl to his nephew, the future Napoleon III of France. During his exile in England, the Emperor sold it to James Hamilton, Marquess and later Duke of Abercorn. Abercorn bought the pearl for his wife, Louisa. The pearl was very heavy and it fell out of its necklace's setting on at least two occasions. The first time, the pearl got lost in a sofa in Windsor Castle; the second time, during a ball at Buckingham Palace. On both occasions, the pearl was recovered. The Hamilton family owned the pearl until 1969, when they sold it at auction at Sotheby's in London. Richard Burton purchased the pearl at the Sotheby's auction for $37,000. He gave it to his wife, Elizabeth Taylor, as a Valentine's Day gift during their first marriage. On one occasion, the pearl went missing in the Burtons' suite at Caesars Palace, Paradise, Nevada. In her book Elizabeth Taylor: My Love Affair with Jewelry, Taylor writes: At one point I reached down to touch La Peregrina and it wasn't there! I glanced over at Richard and thank God he wasn't looking at me, and I went into the bedroom and threw myself on the bed, buried my head into the pillow and screamed. Very slowly and very carefully, I retraced all my steps in the bedroom. I took my slippers off, took my socks off, and got down on my hands and knees, looking everywhere for the pearl. Nothing. I thought, "It's got to be in the living room in front of Richard. What am I going to do. He'll kill me! Because he loved the piece. After few minutes of mental anguish, Taylor looked at their puppies. One of them was apparently chewing on a bone, but nobody gave bones to the puppies. Taylor continues: I just casually opened the puppy's mouth and inside his mouth was the most perfect pearl in the world. It was—thank God—not scratched. Burton sought a portrait of Mary I of England wearing the pearl,
