The Duchess of Edinburgh wowed royal fans when she wore the Lotus Flower Tiara for the first time to the Japan State Banquet at Buckingham Palace on Tuesday evening.
The diamond floral-themed headpiece was last seen on the Princess of Wales at the Diplomatic Reception in 2022, who was absent from the glittering event amid her ongoing cancer treatment.
Sophie's appearance in the tiara sparked questions from royal watchers on social media about who the tiara actually belongs to.
Lauren Kiehna of The Court Jeweller explains why the Princess of Wales does not actually own the jewels and they are not part of her personal collection.
She tells HELLO!: "All four of the tiaras worn by the Princess of Wales belong to the sovereign. They were offered to her as loans, first by Queen Elizabeth II, and more recently by King Charles III and Queen Camilla. Kate has also been loaned other pieces of jewellery, including necklaces, brooches, and earrings, for important occasions."

"The British royal family rarely gives heirloom jewels like tiaras as gifts. They prefer to loan out pieces of jewellery to members of the family like Kate and Sophie, allowing the jewels to be worn but still ensuring that they stay within the family's collection."

In a rare move, the late Princess Margaret bought her own tiara ahead of her wedding to Antony-Armstrong Jones.

However, following Margaret's death in 2002, the tiara was sold to a private buyer at auction by Christie's.
The Princess of Wales's tiara moments
Kate had her first tiara moment on her wedding to Prince William in 2011, when she was loaned the Cartier Halo tiara. The diamond scroll headpiece was given by the late Queen's father, then the Duke of York, to the Duchess of York in 1936 before they became King George VI and Queen Elizabeth.

The diamond and pearl tiara, originally made for Queen Mary in 1913, was gifted by the late Queen to her new daughter-in-law when she married then Prince Charles in 1981.

The then Lady Elizabeth Bowes-Lyon (later the Queen Mother) was given the floral headpiece as a wedding gift from her father, the Earl of Strathmore and Kinghorne in 1923.
