According to HELLO!, the description placed alongside the tiara read, in part: “In the mid-1970s, John Spencer, the 8th Earl Spencer, inherited the tiara. It was subsequently worn by all three of his daughters at their wedding:

Lady Jane in 1978; Lady Sarah in 1980; and finally, Lady Diana the following year, in 1981. The tiara was most recently worn by Celia McCorquodale – niece of the 10th Earl Spencer Charles – at her wedding in the Spring of 2018. The Spencer Tiara is now set to be inherited by Princess Charlotte.”

Charlotte may also be in line to receive another iconic piece of jewellery – Diana’s sapphire engagement ring, which Princess Kate now proudly wears. When Kate married Prince William, she reportedly inherited six pieces from Princess Diana which are set to be worth a total of £16.5million, including Diana’s South Sea pearl earrings, Collingwood earrings, the Saudi sapphire suite and her three-strand pearl bracelet.

Before her death, Diana wrote a “letter of wishes”, in which she explained: “I would like you to allocate all my jewellery to the share to be held by my sons, so that their wives may, in due course, have it or use it.” Kate has also received a number of jewellery pieces from Prince William and King Charles over the years, which could go to Charlotte. These include: the Olympic Cartier set, Ballon Bleu Cartier watch, Promise ring, Eternity band, Green tourmaline and amethyst earrings, shamrock brooch, personalised gold necklace, and amethyst earrings.
