The Duchess of Cambridge was spotted wearing her late mother-in-law's earrings to the Trooping the Colour parade earlier today.
Kate was pictured wearing the diamond and sapphire earrings, once worn by Princess Diana, the late mother of her husband the Duke of Cambridge.
Kate perched in the royal carriage, accompanied by the Duchess of Cornwall and her three children, Prince George, Princess Charlotte and Prince Louis.
The earrings which take a hanging drop formation, are comprised of two blue sapphires each surrounded by a halo of diamonds.

Princess Diana wore the earrings countless times, most notably to the Met Gala in 1996.
The earrings are akin to Princess Diana's engagement ring, which Kate received when she got engaged to Prince William in 2010.
The Duchess of Cambridge's engagement ring is comprised of a blue sapphire, flanked by a circle of diamonds.
Kate recycled her outfit for the event, with the Duchess of Cambridge sporting a white Alexander McQueen blazer dress with a matching two-tone fascinator by Philip Treacy.
Meghan Markle and her husband Prince Harry were absent from the event, as only working members of the Royal Family were permitted.
Kate and William will be absent from any private festivities marking her niece Lilibet's first birthday, due to prior Jubilee commitments in Wales.
Prince Harry and Prince William are set to be reunited tomorrow at the Service of Thanksgiving held at St Paul's Cathedral in London.
The Queen's mobility has impacted her jubilee schedule, with senior royals set to take on Jubilee visits across the country.
