A new royal biography has dropped a bombshell claim: Prince William was so uneasy about Meghan Markle joining the family that he reportedly asked Queen Elizabeth II for a special guarantee before her 2018 wedding to Prince Harry — that she would not wear any of Princess Diana’s jewellery.
The revelation comes from respected royal author Robert Jobson in his 2024 book Catherine, the Princess of Wales: The Biography. It paints a picture of private anxiety and family friction even as the world celebrated what looked like a perfect modern royal love story.
The Claim That Has Royal Watchers Talking
Jobson writes that by the time William was confirmed as Harry’s best man, the brothers’ once-close relationship had already deteriorated. According to his sources:
“I have been told that still concerned about the match, he’d sought assurances from the Queen that Harry’s bride would not be wearing any of Princess Diana’s jewellery, even though his own wife was allowed to wear it.”
The future king apparently wanted a clear boundary drawn around his mother’s most personal possessions — even though Kate Middleton had worn several of Diana’s pieces both before and after her own wedding.
This wasn’t a minor request. In royal circles, access to Diana’s jewellery is deeply symbolic. It represents love, memory, and legacy. William’s reported intervention suggests he was worried about more than just fashion choices.
Meghan’s Wedding Day Look — And What She Didn’t Wear
On 19 May 2018, Meghan walked down the aisle of St George’s Chapel in a breathtaking custom Givenchy gown designed by Clare Waight Keller. The off-the-shoulder silk dress featured long sleeves, a dramatic train, and a veil embroidered with flowers representing all 53 Commonwealth nations — a thoughtful, inclusive touch that won widespread praise.
She wore Queen Mary’s Bandeau Tiara, loaned to her by the Queen herself. It was a powerful statement of acceptance from the monarch.
Notably absent from the daytime ceremony? Any jewellery that had once belonged to Princess Diana.
However, later that evening at the private reception at Frogmore House, Meghan changed into a sleek halter-neck Stella McCartney dress — and slipped on Princess Diana’s aquamarine cocktail ring. The striking turquoise stone, set in diamonds, had been one of Diana’s favourites. Harry had given it to Meghan as a personal link to his mother.

The fact that she wore it at all — even privately — has only added fuel to the story of William’s reported concerns.
Why Diana’s Jewellery Carries So Much Weight
Princess Diana’s jewellery collection is more than just beautiful objects. For William and Harry, these pieces are tangible connections to the mother they lost far too young.
- The sapphire engagement ring Harry gave Meghan originally belonged to Diana.
- Kate has worn Diana’s earrings, bracelets, and other pieces on numerous occasions.
- The aquamarine ring Meghan wore at the reception was a bold, colourful statement piece Diana loved.
William’s alleged request to the Queen suggests he wanted to control who could wear these emotionally charged heirlooms — at least on the biggest day of his brother’s life. Whether it stemmed from protectiveness over his mother’s memory, doubts about the speed of Harry and Meghan’s relationship, or a desire to maintain family traditions is still being debated.
The Brothers Were Already at Odds
Jobson notes that tensions between William and Harry were already high by the time of the wedding. The future king had reportedly expressed concerns about how quickly the romance had developed. Harry has since spoken publicly about feeling that members of his family tried to discourage the marriage.
Despite the private strain, William performed his best-man duties with grace — delivering a warm speech and standing beside his brother in public. The wedding itself was hailed as a spectacular success, watched by millions around the world.
But behind the smiles, Jobson writes, “the Royal Family were all smiles, though privately they were at daggers drawn.”
From Wedding Joy to Family Fracture
The years since have seen the rift between the brothers widen dramatically:
- Harry and Meghan stepped back from royal duties in 2020.
- Their explosive Oprah interview, Netflix series, and Harry’s memoir Spare laid bare deep grievances.
- Reports suggest William has now “cut ties,” believing there is “no way back” for their relationship.
The two brothers have not appeared together publicly in years. They sat separately at King Charles’s coronation, and recent visits by Harry to the UK have not included meetings with William or Kate.
A Story That Resonates Far Beyond Fashion
At its heart, this claim isn’t really about a dress or a ring. It’s about legacy, grief, and the complicated process of welcoming new people into one of the world’s most scrutinised families.
For William, protecting his mother’s jewellery may have felt like protecting her memory. For Harry, sharing those pieces with Meghan was a way of keeping Diana’s spirit alive in his new chapter.
The reported clash between those two instincts reveals just how raw those emotions still were — even a decade after Diana’s death — and how they played out during what should have been a joyous family occasion.
What Happens Next?
Royal biographers and commentators continue to pore over Jobson’s book and similar accounts for clues about the true state of the brothers’ relationship. The Palace rarely comments on such personal claims, leaving the public to piece together the narrative from books, interviews, and occasional sightings.
One thing is certain: the 2018 wedding will forever be remembered not just for its beauty and optimism, but also as a turning point — the last major royal event before the family’s deepest divisions became impossible to ignore.
Whether William’s reported concerns were justified, overly protective, or simply misunderstood, they add another poignant chapter to the ongoing story of two brothers, one lost mother, and a monarchy still adjusting to life in the 21st century.
The sparkle of that Givenchy gown may have dazzled the world, but the quieter story of what happened behind palace doors — and what wasn’t allowed to be worn — continues to fascinate.
