Marilyn Monroe had little interest in jewellery but she did adore the simple pearl necklace given to her by Joe DiMaggio on their honeymoon in January 1954. So much so that she wore it again at their divorce hearing later that year. Elizabeth Taylor, on the other hand, acquired blingy, expensive jewellery like nobody’s business –”Big girls need big diamonds,” she once said. Her collection included the spectacular 16th-century La Peregrina pearl which was part of the Spanish crown jewels. Monroe and Taylor are represented in a show devoted to pearls, opening at the V&A on Saturday.
