New Princess of Wales Kate Middleton reportedly won't inherit Princess Diana's wedding tiara — but Kate's daughter Princess Charlotte will

• Kate Middleton will not inherit Princess Diana's wedding tiara, but her daughter Charlotte will.
• Kate was given the title "Princess of Wales" after the death of Queen Elizabeth II on Thursday.

The new Princess of Wales Kate Middleton may not inherit Princess Diana's wedding tiara, but her daughter Princess Charlotte will.

After Queen Elizabeth II's death on Thursday, Prince William and Kate were officially given the titles of Prince and Princess of Wales by King Charles III in his first address as monarch. The couple already updated their social media handles to reflect the change in roles.

Insider's Jake Epstein and Samantha Grindell reported that no one has held the title "Princess of Wales" since William's mother, Princess Diana.

Although Kate already has the engagement ring that once belonged to Diana, another piece of her wedding jewelry — the diamond-encrusted tiara she wore to her 1981 nuptials — will reportedly be passed down to Charlotte.

According to Hello! Magazine, the Spencer tiara was put on display at an exhibition in London earlier this year, accompanied by text that said Diana's eldest granddaughter would one day own the diadem.

"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 text read, per the outlet."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."

Representatives for the Prince and Princess of Wales did not immediately respond to Insider's request for comment.

Hello! writes that the tiara currently remains in the Spencer family. Vogue reported in June that the small crown was assembled in 1930 by luxury jeweler Garrard from old Spencer jewels and diamonds. The central, floral piece was a gift to Lady Cynthia Hamilton for her wedding to Diana's grandfather.

Celebrity hairdresser Sam McKnight, who worked with Diana, also told the publication that the late princess liked the Spencer tiara because it was light and didn't give her headaches.
