What happened to Anna's jewelry in the biography, Empty Mansions?

Anna left Huguette several pieces of jewelry after her death. This jewelry was kept in a safe deposit box at a Citibank. On two occasions the jewelry went missing, first when someone accessed the box and a second time when a clerical mistake caused the box bill not to be paid. Citibank took advantage of Huguette’s dislike of publicity to force her to accept less than the appraised value for the jewelry.
