Princess Catharina-Amalia of the Netherlands Sparkles in Repeat Tiara at Her First State Banquet

The future queen of the Netherlands might officially have a favorite tiara!

Princess Catharina-Amalia of the Netherlands is sparkling at her first state banquet.

On April 17, the future queen of the Netherlands attended her first official diplomatic dinner celebrating the visit of King Felipe and Queen Letizia of Spain. Princess Amalia, 20, shimmered at the Royal Palace in Amsterdam in the Ruby Peacock Tiara with a matching necklace and earrings paired with a navy cape dress.

The young royal has reached for the same headpiece before! Princess Amalia first wore the Ruby Peacock Tiara to the royal wedding of Crown Prince Hussein and Princess Rajwa of Jordan in June 2023.

Queen Letizia and Amalia’s mother, Queen Maxima, also glittered in dazzling head-toppers at the state banquet, along with former queen Princess Beatrix and Princess Margriet of the Netherlands. Blue was the color of the night, with all the royal women matching in shades of the hue.

Hosting the King and Queen of Spain during their two-day stay in the Netherlands and making her state banquet debut with them was a fitting choice for Princess Amalia, who has a unique connection to their country. The Princess of Orange recently lived in Spain after security threats in the fall of 2022 prevented her from continuing to live in student housing in Amsterdam.

Spain was a natural pick for the princess. Because Queen Maxima is originally from Argentina, Princess Amalia is fluent in Spanish. Plus, in another sweet tie to the country, King Willem-Alexander and Queen Maxima first met in Seville.

During his speech at the state banquet, King Willem-Alexander addressed his eldest daughter's stay in the country.

"Last year, circumstances required her to live in Madrid. From there, she was able to continue her studies at the University of Amsterdam. This was made possible by the kind efforts of many of your compatriots and yourselves," the Dutch monarch said in his speech, delivered in English, to King Felipe and Queen Letizia. "A touching demonstration of friendship at a difficult time. I'd like to express my heartfelt thanks to you and to everyone else who helped arrange this."

Princess Amalia previously revealed that she's a longtime fan of royal jewels like tiaras.

"I love tiaras," the royal said in her biography, published in 2021 before her 18th birthday. "Show me a tiara, and I'll know where it came from. I can recognize all the tiaras of Europe."

"I used to put them on from my mother," Amalia explained. "Then there would be one on her make-up table, and I would have it directly on my head."

While the future queen ticked an exciting milestone off her royal to-do list by attending the state banquet, the glam event is not her first time wearing a tiara.

Queen Maxima and King Willem-Alexander’s eldest daughter made her tiara debut in June 2022 at Princess Ingrid Alexandra of Norway's 18th birthday gala, where she wore the Dutch Star Tiara. The headpiece was a sentimental choice, as it was the same sparkler that Queen Maxima wore at her wedding in 2002.

Princess Amalia had two tiara moments in 2023, kicking off with the wedding of Crown Prince Hussein to Princess Rajwa in June. The heir to the Dutch throne shimmered in the Ruby Peacock Tiara, which matched her red gown. The combination appeared to be a hit with the princess, who wore the tiara and gown together again for the wedding of Prince Ferdinand and Princess Marie of Schwarzenberg in July, The Court Jeweller reported.

In October, she sported the Sapphire Necklace Tiara to the 18th birthday bash for Crown Prince Christian of Denmark, a fellow heir.

Princess Amalia continued color-coordinating for the party in Denmark and matched her sapphire tiara to her cerulean cape dress.

Despite its name, the Sapphire Necklace Tiara can’t be switched into a necklace. The Court Jeweller reported that the sparkler was fashioned from a dismantled necklace that belonged to Amalia’s ancestor, Queen Emma.

While she's still a university student, Princess Catharina-Amalia has been slowly introduced to more elements of royal life as she prepares to become queen someday. While some monarchs reign until their deaths, the Dutch royals traditionally abdicate the throne for their heir.

However, Princess Amalia hopes there are many years before her father steps aside.

Princess Amalia told biographer Claudia de Breij that she didn't feel ready to be monarch yet and would ask her mother, 52, to step in should her father, 56, unexpectedly die in the near future.

"I said to my father, 'You just keep on eating healthy and exercising a lot,' " she said.
