RF. THE VAULTS ARE OPEN! King Charles III just unlocked history… and you won’t believe the unexpected treasure Catherine chose to wear!

The British royal family has long used jewelry as a form of visual storytelling, with historic pieces often appearing at moments of diplomatic and ceremonial importance. One such moment occurred during a state banquet at Windsor Castle, when the Princess of Wales, Catherine, wore the Indian Circlet tiara—an historic jewel that had not appeared publicly for many years. The occasion marked a notable moment in modern royal fashion, combining heritage, continuity, and contemporary presentation.

The event, held in honor of German President Frank-Walter Steinmeier, brought together senior members of the royal family and highlighted the evolving way historic royal jewels are worn and presented today.

A Day Marked by Diplomacy and Tradition

The official visit began earlier in the day with a formal welcome at Windsor Castle, where the Prince and Princess of Wales greeted the German president. Catherine appeared in a structured Prussian blue coat, a color historically associated with diplomacy and European heritage. The shade has long-standing historical roots in Germany, having originated in Berlin in the early 18th century, and its use was widely interpreted as a respectful and appropriate choice for the occasion.

Her daytime ensemble was completed with the Prince of Wales feathers brooch, a historic jewel traditionally associated with the title. The brooch dates back to the 19th century and has been worn by several Princesses of Wales, reinforcing continuity within the role. Catherine also wore sapphire and diamond cluster earrings that have been part of the royal collection for decades and were previously worn by Diana, Princess of Wales. The earrings are well documented and are frequently associated with formal royal engagements.

The State Banquet at Windsor Castle

As evening fell, Windsor Castle hosted a formal state banquet, an event that traditionally allows for the display of the royal jewelry collection. For this occasion, Catherine selected the Indian Circlet tiara, a historic piece with origins in the mid-19th century. The tiara was originally designed under the direction of Prince Albert and was created using diamonds taken from a necklace belonging to Queen Victoria.

The Indian Circlet has been worn by several royal figures over the generations, including Queen Victoria and Queen Elizabeth The Queen Mother. While it has remained part of the royal collection, it has rarely been seen in public in recent decades, making its appearance at the banquet particularly notable.

Catherine paired the tiara with an evening gown by British designer Jenny Packham, a designer she has frequently worn for major formal occasions. She also wore diamond chandelier earrings from the royal collection, creating a cohesive look that balanced historic significance with modern styling.

Notably, the tiara was worn with her hair styled down rather than in a traditional updo. While entirely within modern royal norms, this presentation offered a contemporary interpretation of a historic piece, reflecting how royal dress codes have gradually evolved while still respecting tradition.

Queen Camilla and Continuity in Royal Jewelry

Queen Camilla also made a significant jewelry choice for the evening, wearing the Girls of Great Britain and Ireland tiara. This tiara is among the most recognized in the royal collection and was frequently worn by Queen Elizabeth II throughout her reign. Its continued use by Queen Camilla reflects the established practice of passing key jewels between reigning queens and consorts.

In addition to the tiara, Queen Camilla wore a modified version of the Greville emerald necklace, a well-documented piece from the Greville bequest. Over time, the necklace has been adapted for wearability, demonstrating how historic jewels can be carefully altered while preserving their original craftsmanship. Such adaptations are a recognized and accepted practice within the management of the royal jewelry collection.

Other Members of the Royal Family

Other senior royals attending the banquet also drew attention for their jewelry choices. The Duchess of Gloucester wore the Cartier India tiara, a piece with a long association with her role and one that has been worn consistently at major state events. The tiara is historically significant and reflects the enduring relationship between the British royal family and Cartier.

The Princess Royal, Anne, wore the aquamarine pineflower tiara, a piece closely associated with her personal collection. Known for favoring consistency in her jewelry choices, Princess Anne’s selection reinforced her long-standing approach to royal dress: practical, symbolic, and understated.

The Duchess of Edinburgh, Sophie, attended wearing her aquamarine necklace tiara, a versatile piece that can be worn as either a tiara or necklace. She complemented it with a high jewelry suite from Graff, a contemporary jewelry house with a long history of working with royal clients.

The Role of Jewelry in Modern Royal Representation

Royal jewelry is more than ornamentation; it serves as a visual link between past and present. Each piece carries documented provenance, historical context, and ceremonial meaning. The careful selection of jewels for state occasions reflects not only personal style but also institutional continuity.

In recent years, senior royals have increasingly balanced tradition with accessibility, often choosing pieces that are historically significant while styling them in ways that feel modern and relatable. This approach aligns with the broader evolution of the monarchy, which seeks to maintain relevance while honoring centuries-old customs.

A Reflection of Stability and Heritage

The appearance of historic tiaras and jewels at the Windsor state banquet reinforced the monarchy’s role as a custodian of national heritage. By wearing established pieces from the royal collection, members of the royal family signal continuity, respect for history, and stability—qualities that are particularly important during diplomatic events.

The Princess of Wales’s choice to wear the Indian Circlet tiara did not represent a break from tradition, but rather a reaffirmation of it, presented through a contemporary lens. Similarly, Queen Camilla’s jewelry selections reflected her role in maintaining established royal customs.

Conclusion

The Windsor Castle state banquet offered a rare opportunity to see some of the most significant pieces from the royal jewelry collection worn by multiple generations of the monarchy. From the Indian Circlet tiara to the Girls of Great Britain and Ireland tiara, the evening highlighted how historic jewels continue to play an important role in royal diplomacy and ceremonial life.

By combining documented heritage with modern presentation, the royal family demonstrated how tradition can remain relevant in the present day. For historians, jewelry experts, and royal watchers alike, the event served as a reminder that royal jewels are not static artifacts, but living symbols of continuity, responsibility, and public service.
