Kate Middleton and other members of the Royal Family made a touching tribute to Queen Elizabeth II by wearing brooches with her portrait on them.
The occasion was in honour of the President of South Africa, Cyril Ramaphosa.
To mark the occasion, Middleton wore jewellery to honour late, senior members of the royal family.
The Princess of Wales stunned at the white-tie event, wearing her broach which was surrounded by diamonds and placed over a yellow ribbon.
She also wore a pearl bracelet belonging to the late Queen and a pair of Diana's earrings.
Camilla, Queen Consort, and Sophie, Countess of Wessex also wore the brooch.
The tiara Kate opted for was also regularly worn by Diana; it's the Lover's Know Tiara, which was made in 1914 and features diamonds and pearls.
During the Queen's funeral on 19 September, Middleton wore the late Queen’s pearl choker necklace, the same one she wore to the Duke of Edinburgh’s funeral, which was not a state funeral.
The necklace was a gift from Japan in the 1970s, and consists of four rows of pearls with a central diamond clasp in a curved shape.
The Queen also reportedly wore the necklace to Margaret Thatcher’s 70th birthday.
Back in 1982, Her Majesty was said to have lent it to Princess Diana to wear at a banquet at Hampton Court Palace.
The necklace was then passed on to Catherine in 2017, who wore it to the Queen and Prince Philip’s 70th wedding anniversary.
As King Charles explained in his first address to the nation on 9 September: "With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations, helping to bring the marginal to the centre ground where vital help can be given."
The news marks the first time the Princess of Wales title has been given to a member of the royal family since Princess Diana held the title through her marriage to Prince Charles, who she divorced in 1996.
According to a royal source, the new Prince and Princess of Wales were 'focused on deepening the trust and respect of the people of Wales over time'.
"The Prince and Princess of Wales will approach their roles in the modest and humble way they’ve approached their work previously," they continued, before revealing Kate's response to the news as they said: "The new Princess of Wales appreciates the history associated with this role but will understandably want to look to the future as she creates her own path.”
