Queen Elizabeth subtly paid tribute to her late husband, Prince Philip, ahead of the late Duke's 100th birthday.
The 95-year-old hopped on a video call, where she wore a diamond and ruby brooch in the shape of a butterfly — a wedding gift from Dowager Countess of Onslow.
"Today The Queen held virtual Audiences with incoming Ambassadors via video link from Windsor Castle to Buckingham Palace," the Royal Family Twitter account captioned a photo of the matriarch. "There are more than 170 Ambassadors and High Commissions based in London. Each have an Audience of The Queen shortly after taking up their role."
The Queen last wore the piece of jewelry in August 2019, and before that, she wore it in January 2012.
On June 10, it was revealed that the Queen honored Prince Philip by planting a rose at Windsor Castle.
"Last week, The Queen was given a Duke of Edinburgh rose to mark what would have been The Duke's 100th birthday," the caption read. "The rose was gifted by @the_rhs , of which The Queen is Patron. Named in The Duke's memory, the rose is planted in the East Terrace Garden, Windsor Castle. In 1956 His Royal Highness founded The @dofeuk Award scheme which he described as a ‘do-it-yourself growing up kit.’"
The message continued, "For every Duke of Edinburgh Rose sold, a donation will be made to The Duke of Edinburgh’s Award Living Legacy Fund. The Fund will give a million more young people, from all circumstances and backgrounds, the opportunity to achieve a DofE Award. Each rose purchased will help establish new DofE centres, deepen existing support, and train thousands more Leaders and volunteers. Head to our stories to find out more ➡️."
Kate Middleton, Prince William, Prince Charles, Camilla and Princess Eugenie also wrote sweet messages about Philip.
