Kate wore the Queen Mother's diamond and sapphire fringed earrings on Wednesday evening
The Queen Mother was originally pictured wearing the statement pair while attending the play Rookery Nook by Ben Travers in 1986. Since her sad passing in March 2002, at the age of 101, very few royals including Princess Anne, Duchess Camilla and of course, Kate, have been lucky enough to wear pieces from her collection.
The Queen famously shared a close bond with her mother, as well as her sister Princess Margaret, so Kate's lovely gesture on Wednesday night will no doubt have been appreciated by Her Majesty.
Queen Elizabeth shared a close bond with her mother
On the eve of the Queen Mother's funeral, The Queen delivered a heartfelt speech to the nation, capturing the spirit of her "beloved mother."
"My family and I always knew what she meant for the people of this country and the special place she occupied in the hearts of so many here, in the Commonwealth and in other parts of the world," she said.
"But the extent of the tribute that huge numbers of you have paid my mother in the last few days has been overwhelming. I have drawn great comfort from so many individual acts of kindness and respect."
Kate previously wore the Queen Mother's earrings to an event in 2015
It's not the first time that Duchess Kate has worn the Queen Mother's favourite sapphire earrings to an engagement. Royal fans might remember the mum-of-three's glamorous appearance at the 100 Women In Hedge Funds Gala Dinner, held at the Victoria and Albert Museum in 2015. She wore a crimson floral dress by Erdem for the event and sported her signature bouffant blow dry.
