While Kate Middleton was unable to attend Royal Ascot on June 18, abruptly canceling her appearance at the last minute, Queen Camilla arrived alongside King Charles, Prince William, and Prince Saud bin Khalid Al Saud. For the chic occasion, The Queen matched her green dress and hat to a Royal Family heirloom, which has been handed down from Queen Elizabeth. As a result, Queen Camilla's Royal Ascot outfit included a "striking" and valuable tribute to her late mother-in-law.
Jewelry expert Maxwell Stone, of British retailer Steven Stone, analyzed Queen Camilla's brooch—known as the Cambridge Cluster Emerald and Diamond Brooch—which has an important royal history. "Queen Camilla's brooch originally belonged to Queen Mary, the grandmother of Queen Elizabeth II, and was passed down to the late monarch in 1953—the year of her coronation," Stone explained.
