Kate Middleton wears Princess Diana's pearl bracelet at Trooping the Colour as Charlotte mirrors her mother
Kate Middleton made a meaningful appearance at the Trooping the Colour ceremony on Saturday, stepping out with her children in coordinated looks.
The Princess of Wales, 44, drew attention in a baby blue Catherine Walker ensemble paired with a coordinating Philip Treacy hat for the annual military parade celebrating King Charles III's official birthday.
But it was her jewelry choice — and Princess Charlotte's matching accessory — that quickly sparked conversation among royal watchers.

Kate wore Princess Diana's iconic three-strand pearl bracelet, a statement fashion piece that paid tribute to the late royal.
Meanwhile, sitting across from her mother in the royal carriage, 11-year-old Princess Charlotte appeared to wear a remarkably similar bracelet.
The bracelet carries significant royal history.
Designed by jeweler Nigel Milne, Diana famously wore the pearl-and-diamond piece throughout 1989, including at a Birthright charity event, a performance of "The Masked Ball" at the London Coliseum and, most memorably, with her famed "Elvis" gown and the Queen Mary Lover's Knot Tiara at a state banquet in Hong Kong, according to InStyle.
Following Diana's death in 1997, Prince William inherited the bracelet and later gifted it to Kate.

During Trooping the Colour, Princess Charlotte wore a white dress accented with blue details that coordinated with Prince George's baby blue tie as the siblings rode through London alongside their mother.
Prince Louis joined his family in the carriage while Prince William participated in the military procession on horseback.
The carefully coordinated family appearance came as Kate joined King Charles, Queen Camilla and senior royals for Trooping the Colour, one of the most significant events on the royal calendar.
Camilla wore a scarlet ceremonial coat accented with gold detailing and a dark-colored hat topped with a white feather plume, while Charles appeared in full military dress uniform adorned with gold braiding, medals and a blue sash across his chest as he greeted well-wishers during the annual celebration of his official birthday.
Meanwhile, the Princess of Wales' appearance marked another high-profile public engagement as she continues to resume royal duties following her cancer diagnosis and treatment.

As Kate continues her return to the spotlight, royal experts believe that her influence within the monarchy has only strengthened in recent years.
"I think the 'Kate Era' began the moment she and Prince William exchanged vows in 2011," Christopher Andersen, author of "Kate!," recently told Fox News Digital. "No one in recent memory has had a greater impact on the monarchy than Kate."
"Kate was already bringing her own special brand of magic to the monarchy before she was sidetracked by her stunning cancer diagnosis in 2024," Andersen shared.
"From the beginning, comparisons with Princess Diana were inevitable — both were charismatic, compassionate, beautiful, smart, stylish and, most importantly, they could connect with people on a very human level."

Beyond wearing one of Diana's most treasured pieces of jewelry, Kate has previously honored the late Princess of Wales.
For Trooping the Colour last year, she stepped out in a powder-blue look that echoed a memorable outfit worn by Princess Diana during the 1988 celebration.
Diana famously appeared in a similar blue-green ensemble accented with white lapels, creating a visual parallel that royal observers quickly noted.
The annual celebration featured more than 1,500 military personnel, 200 horses and 400 musicians before concluding with the traditional Buckingham Palace balcony appearance and flypast.
