Princess Isabella of Denmark stuns in first official gala portraits to mark her 18th birthday

Princess Isabella of Denmark has marked her 18th birthday with a series of official portraits — and she’s wearing her first tiara.

The eldest daughter of King Frederik X and Queen Mary posed for several photographs at Knight’s Hall at Amalienborg Palace — the Danish royal family’s main residence located in the capital city of Copenhagen.

On Monday, the Danish Royal House released Isabella’s first official gala portraits, just one day after her milestone birthday.

The palace captioned the images, “18 years ago today Her Royal Highness Princess Isabella was born. The birthday itself is marked with the publication of the Princess’s first official gala portraits.

“The princess is photographed in the Knight’s Hall of Frederick VIII’s Palace in Amalienborg, and on the portraits Her Royal Highness wears the Order of the Elephant with a star chest… and a miniature Order portrait of her father, His Majesty the King.”

In the images, the princess can be seen wearing a satin orange off-the-shoulder ballgown paired with a blue Order of the Elephant sash and regalia.

She topped off her regal look with a sentimental nod to her father by wearing a miniature portrait of him on her sash.

Isabella, who is second in line to the throne after her brother Crown Prince Christian, 19, accessorized with a pair of diamond turquoise earrings.

Arguably the most eye-catching element of Isabella’s look was her diamond tiara, which had been gifted to her by her grandmother, Queen Margrethe, who abdicated the throne in January 2024.

The Danish Royal House confirmed that the queen, 85, gave Isabella the floral diadem, which features 11 rosettes of “daisy-like flowers” in a sweet nod to Margrethe, who is lovingly nicknamed Daisy by her loved ones.

“The tiara is a so-called ‘bandeau,’ a headband in French, as the relatively narrow tiara is intended to be worn almost horizontally as a hair band,” the palace said in a statement.

“The tiara was made in the late 19th century and belonged to Crown Princess Margareta of Sweden. After her untimely death in 1920, her daughter, Princess Ingrid, received the tiara as a confirmation gift and brought it to Denmark upon her marriage to the later Frederik IX.”

“Like many other pieces of the Royal House’s jewelry, the tiara has multiple functions, as it can be disassembled and used as a bracelet,” the statement concluded.

One day before her birthday, the royals shared a look at some scrapbook images of their family images.

In one snap, Queen Margrethe can be seen holding baby Isabella shortly after she was born in 2007.

“Little glimpses from childhood to 18 years old,” the Danish royals wrote on Instagram.

“On the occasion of Her Royal Highness Princess Isabella’s 18th birthday on Monday, Their Majesties the King and Queen share here a selection of memories.”
