King Charles and Queen Camilla dazzled Windsor Castle on November 18 as they welcomed more than 900 ambassadors and high-ranking diplomats for the annual Diplomatic Reception — one of the most prestigious events on the royal calendar.

But while global dignitaries gathered beneath the castle’s glittering chandeliers, one senior royal was noticeably missing: the Princess of Wales.

A Royal Night Without Kate

Princess Kate was absent for the second consecutive year. Earlier that day, she delivered her first public speech in two years at The Future of the Workforce Summit, urging business leaders to prioritise “time and tenderness” in early childhood development — a message warmly received.

Although she has completed chemotherapy and is in remission, the princess continues to scale back public engagements to focus on her health and family. Her last appearance at a Diplomatic Reception was in December 2023, when she captivated the room in a blush-pink Jenny Packham gown and the Lover’s Knot Tiara.

Prince William attended the reception alone, joining the king and queen in representing the family.

A Historic Return to Windsor

This year marked the first time since 2001 that the reception was held at Windsor rather than Buckingham Palace, which remains under renovation. Traditionally a white-tie, tiara-filled evening, the event honours the global diplomatic corps and reinforces the monarchy’s ties with international partners.

Queen Camilla’s Glittering Tribute

Though Kate was missed, Queen Camilla drew her own spotlight by wearing the Greville Emerald Kokoshnik Tiara — the same striking diadem Princess Eugenie famously wore at her 2018 wedding.

Royal watchers believe the choice was a subtle nod of support for Eugenie and the York family, who have faced persistent scrutiny following Prince Andrew’s royal downfall and renewed public attention around his past associations.

The tiara itself is a century-old masterpiece: commissioned in 1919 by Dame Margaret Greville, designed by Boucheron, and built around a nearly 100-carat cabochon emerald. Experts estimate its value at over £10 million, thanks to its rarity and craftsmanship.

Looking Ahead

Princess Kate is expected to make a full-glam return next month at the German state banquet at Windsor — a moment royal fans are eagerly anticipating.
