Several iconic pieces have disappeared from public view since 1997
The late Princess Diana left specific instructions regarding the fate of her jewellery in her will, it has been revealed.
Leaving the precise division to the discretion of her executors, Diana wrote: "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."
The reality of her collection proved far more complicated than a simple inheritance, however.
While Diana owned or received many celebrated pieces as gifts, numerous others were merely loans from the Spencer family, the Royal Collection Trust, the monarchy's private holdings, or prestigious jewellery houses.
The world's most recognisable engagement ring, featuring a 12-carat Ceylon sapphire, is now worn by Catherine, The Princess of Wales.
Catherine regularly wears several of Diana's pearl pieces, including the four-strand pearl choker, the Collingwood teardrop pearl earrings gifted to Diana by Charles on their 1981 wedding day, and diamond and South Sea pearl earrings.
From the Saudi Suite, Catherine has been seen wearing what appears to be a redesigned necklace and the detachable drop-down earrings, styled in her characteristically understated manner.
Meanwhile, Meghan Markle received Diana's aquamarine ring from Harry in 2018, a piece the princess had commissioned from Asprey as a symbol of her post-divorce independence.
The emerald-cut stone, sourced from a renowned Brazilian mine and given to Diana by her close friend Lúcia Flecha de Lima, was designed to replace her engagement ring.
The Duchess of Sussex wore the ring to her wedding reception, though she has only displayed it publicly on one other occasion.
She also frequently sports a yellow gold Cartier Tank Française that belonged to Diana, along with a diamond tennis bracelet and butterfly stud earrings.
Several of Diana's most iconic pieces have disappeared entirely from public view since 1997.
The sapphire and diamond pearl choker, which she wore dancing with John Travolta at the White House and to the Serpentine Gallery in her famous "revenge dress," remains unseen despite being owned by her sons.
The extravagant Crescent set, a striking modern suite of diamonds and sapphires presented to Diana by the Sultan of Oman, represents one of the most notable examples of her "lost" jewels.
Diana's costume jewellery, frequently purchased from London's Butler & Wilson, has similarly vanished without trace. She delighted in wearing chunky pieces when meeting children and took particular pleasure when the press mistakenly reported her budget accessories as genuine.
The Spencer Tiara, worn by Diana on her wedding day, returned to her family and is now held by her brother Charles Spencer. It was last seen publicly on Diana's niece Celia McCorquodale at her 2018 wedding.
Kim Kardashian acquired one of Diana's most striking pieces in 2023, paying £160,000 for the Attallah Cross at auction. The substantial 1920s Garrard necklace, featuring amethysts and diamonds, belonged to Diana's friend, jeweller Naim Attallah, who lent it to her on multiple occasions.
Diana memorably paired the cross with a dramatic purple velvet high-collared gown at a 1987 Birthright charity gala. Ms Kardashian debuted the piece at the 2024 LACMA gala in Los Angeles.
The Swan Lake Suite, a custom Garrard creation comprising 187 diamonds and five South Sea pearls, was incomplete at Diana's death and subsequently sold by the jeweller.
Queen Camilla has worn Crown-owned jewels previously sported by Diana, most notably a large emerald and diamond brooch reset from a necklace the Queen Mother gifted Diana in 1981.
