Kate Middleton wore a pearl necklace that honored the Queen and Prince Philip's love story at his funeral

• Kate Middleton paid tribute to Prince Philip by wearing a pearl necklace belonging to the Queen.
• She wore the necklace once before, to the Queen and Philip's 70th anniversary dinner.
• Middleton was among the 30 people who attended Philip's funeral on Saturday.

The Duchess of Cambridge paid tribute to Prince Philip by wearing a necklace with a special connection to the duke at his funeral.

Kate Middleton was among the 30 people who attended the ceremony at St George's Chapel, Windsor Castle, on Saturday.

Middleton wore a Four-Row Japanese Pearl Choker, which was borrowed from the Queen and previously worn by Princess Diana, The Independent reports.

The royal also wore a black Catherine Walker coat, a matching face covering and fascinator, and pearl drop earrings which belong to the Queen, the Mail Online reports.

The duchess appears to have only worn the necklace publicly once before, at the Queen and Duke of Edinburgh's 70th wedding anniversary dinner at Windsor Castle in November 2017.

The Queen and Philip became the first monarch and consort to reach the milestone, making the duke the longest serving consort in British history.

After meeting at a wedding as children, Elizabeth and Philip made their engagement official in July 1947. They were 21 and 26-years-old at the time.

The couple reached their 73rd wedding anniversary in November 2020, and the duke was due to celebrate his 100th birthday in June.

Middleton appeared to have a close relationship with her grandfather-in-law.

Prince William referenced Middleton and Philip's relationship in a written tribute to his grandfather on Instagram after his death.

"I will always be grateful that my wife had so many years to get to know my grandfather and for the kindness he showed her," William wrote.

He went on to write about his children's relationship with Philip, saying: "I will never take for granted the special memories my children will always have of their great-grandpa coming to collect them in his carriage and seeing for themselves his infectious sense of adventure as well as his mischievous sense of humor."
