Princess Charlotte quietly honoured her late great-grandmother, Queen Elizabeth, with special brooch

As the youngest royal present at the funeral of Queen Elizabeth II, Princess Charlotte made sure to pay a touching tribute to her "Gan Gan" with a small detail in her mourning attire.

The seven-year-old royal wore her first brooch publicly; a horseshoe brooch on the left side of her black coat.

It was a sweet and poignant tribute to her great-grandmother – who was well known for her love of horses.

And it is a love shared by Charlotte; as Princess Kate was quoted in 2018 as saying that her only daughter had inherited the Queen's passion for horses.

Her Majesty gifted the young princess with the sentimental piece of jewellery, which is made of diamonds.

There is no doubt that Her Majesty would have approved her great-granddaughter's sartorial choice today.

Charlotte also wore a matching black hat, a custom for British women attending formal events and another first for the princess.

Both Charlotte and her older brother Prince George, nine, had shown composure beyond their years during the emotional service.

Tugging at royal fans' heartstrings, the young princess was also seen instructing her brother that he needed "to bow" as the Queen's coffin went past.

Their little brother Prince Louis, four, was deemed too young to attend.

The moment comes after Princess Kate made a heartbreaking admission to Australia's Governor-General ahead of the funeral, revealing how her children were handling the passing of their great-grandmother.

Governor-General David Hurley said in an interview: "The younger one [Louis] is now asking questions like, 'Do you think we can still play these games when we go to Balmoral and things like that, cause she's [the Queen] not going to be there?'"

Hurley also recalled Kate telling him that George was just now "realising how important his great-grandmother was" amid global grief over her death.
