The question of which tiara Princess Catherine, the Princess of Wales, should debut next has become a favorite debate among royal watchers. With Queen Camilla recently bringing several long-unseen pieces back into rotation — including the Greville Emerald Kokoshnik Tiara and the Aquamarine Ribbon Tiara — hopes are high that more treasures will emerge from the vault. Catherine’s surprise debut of the Strathmore Rose Tiara in 2023 only fueled that excitement.

Below are the strongest contenders royal experts believe Catherine could wear next — each with history, symbolism, and glamour fit for a future queen.

1. The Strathmore Rose Tiara

A sentimental piece gifted to the future Queen Elizabeth (later the Queen Mother) by her parents, the Strathmore Rose is delicate, romantic, and rarely seen. Long rumored to be too fragile to wear, its unexpected appearance on Catherine proved otherwise. Fans hope she brings it back again — this time with proper photographs and lighting to show off its intricate floral design.

2. The Greville Emerald Kokoshnik Tiara

First worn publicly by Princess Eugenie on her wedding day, this tiara was part of a massive bequest from Dame Margaret Greville. Its striking central emerald and Kokoshnik silhouette make it both modern and commanding. Experts believe Catherine would wear it beautifully, especially paired with emerald earrings already in her rotation.

3. The Aquamarine Ribbon Tiara

A favorite of Sophie, Duchess of Edinburgh, and recently worn by Queen Camilla, this lighter, more flexible tiara is an elegant option for state banquets. With Catherine’s preference for streamlined silhouettes, this could be a natural fit.

4. Queen Mary’s Fringe Tiara

One of the most iconic pieces in the British collection, this tiara has served as the bridal diadem for three royal brides: Princess Elizabeth in 1947, Princess Anne in 1973, and Princess Beatrice in 2020. Though traditionally tied to royal weddings, its design — sharp, radiant, and queenly — makes it a strong candidate for Catherine at future state occasions.

5. The Queen Mary’s Bandeau Tiara

Famously worn by Meghan Markle, this diamond-and-platinum tiara features a detachable brooch center. Despite social-media debates around it, the piece itself is a timeless Mary-era jewel with stunning craftsmanship. Many royal watchers would love to see Catherine revive it, separating the tiara from any lingering public drama.

6. Queen Mary’s Diamond Lozenge Tiara
This tiara’s whereabouts have been the subject of speculation — some believe it was sold, others think it remains in the vault. If it reappeared on Catherine, it would be a sensational surprise. Its geometric design allows for pearl accents that can be added or removed.

7. Queen Mary’s Russian Bandeau Tiara
A lesser-known jewel once worn by Princess Margaret, this tiara features a dramatic central sapphire — a striking match for Catherine’s sapphire engagement ring. A Catherine appearance in this piece would undoubtedly be a headline moment, merging history, symbolism, and cohesive gemstone styling.

Why These Choices Matter
The British royal family owns one of the world’s largest and most historically rich tiara collections. Unlike other monarchies where only queens may wear the grandest pieces, the British vault is extensive enough for senior royal women to share and rotate among dozens of designs. Each tiara worn is not only a fashion decision, but also a gesture of continuity, heritage, and storytelling through jewelry.

With a major state banquet scheduled for December, anticipation is building once again. Whether Catherine reaches for something familiar — or surprises the world with a long-hidden masterpiece — her next tiara choice is set to captivate global royal fans.
