The Princess of Wales paid tribute to her late grandmother-in-law during her coffin procession by wearing a leaf brooch made of diamonds and pearls that belonged to the Queen.
The monarch, who passed away peacefully last Thursday aged 96, was known for lending out her jewellery to other royals.
The Duchess had worn the brooch previously in 2017 at the Tyne Cot Commonwealth War Graves Cemetery in Ypres, Belgium, at a commemoration ceremony to mark the centenary of the Battle of Passchendaele.
The Queen herself was photographed wearing the brooch on her 73rd birthday in 1999 during an official visit to South Korea.
Kate also commemorated the previous Princess of Wales by wearing Diana’s pearl drop earrings during the procession through central London.
The Duchess of Sussex paid tribute to Her Majesty in a similar way as she sported pearl and diamond stud earrings that were a gift from the Queen.
Meghan had worn the same earrings during her first and only solo engagement with the Queen a month after her wedding to Prince Harry.
In 2018 she accompanied Her Majesty to a ceremony to open the new Mersey Gateway Bridge in Widnes, Chester.
While receiving the Queen’s coffin to Buckingham Palace on Tuesday evening Kate was seen wearing another pair of her favourite earrings.

The pearls worn by Kate and Meghan are thought to be symbolic of grief.
Since Queen Victoria pearls have been associated with mourning, as the famous ruler never wore colour or bright jewels after the death of her husband Prince Albert.
Instead she favoured jet and pearls, with pearls signifying tears in the 19th century.
