The jewel at the centre of attention is the Greville Emerald Kokoshnik Tiara, a lavish Boucheron creation crafted in 1919. The tiara is distinguished by its large central cabochon emerald, framed by pavé diamonds and smaller emeralds in a design inspired by the ornate kokoshnik headpieces worn at the Russian imperial court.
Its history is equally significant. Originally owned by Dame Margaret Greville, the piece was later bequeathed to Queen Elizabeth, the Queen Mother, before eventually becoming part of the modern royal collection. Queen Elizabeth II later loaned it to Princess Eugenie for her 2018 wedding to Jack Brooksbank, making it one of the most memorable and meaningful “something borrowed” moments in recent royal history.
Camilla’s decision to bring out this particular tiara during the Diplomatic Corps reception at Windsor Castle on November 18, 2025, has sparked considerable commentary — and not merely for its striking beauty. Given ongoing tensions around Eugenie’s family, especially following Prince Andrew’s scandals and the loss of his royal titles, many observers interpret the choice as a subtle but purposeful message. Some see it as a gesture of quiet support toward Princess Eugenie and Princess Beatrice during a period of uncertainty.
Jewellery experts also believe the selection was far from accidental. Gemologist Oliver Hobart suggested that Camilla’s choice “feels very deliberate” — a decision carrying symbolic weight rather than being purely aesthetic. Others view it as Camilla’s way of reasserting her position by wearing a piece previously associated with a junior royal, subtly reinforcing her own senior status within the monarchy.
To complete the look, Camilla wore a cream-embroidered Fiona Clare gown, paired with a diamond serpent necklace and matching earrings — an ensemble that appeared both regal and strikingly personal. Images from the reception highlight the elegance of the moment as King Charles III, Queen Camilla, and the Prince of Wales greeted guests in the grand setting of Windsor Castle.
Ultimately, this was far more than a fashion highlight. It was a statement — one that signals Camilla’s awareness of the shifting dynamics within the Royal Family and her willingness to use historic jewels to communicate with a subtlety that speaks louder than words.
