The Duchess of Cambridge Kate Middleton was seen in an all-black ensemble that consisted of a Roland Mouret dress at Prince Philip's funeral. However, what stood out in the look was a gorgeous pearl and diamond neckpiece she wore.
Featuring four strands of pearls and a diamond clasp, the piece was reportedly a gift to Queen Elizabeth II from the Japanese government. Additionally, the heirloom was worn by Princess Diana as well, in 1982.
