The four small but important details you missed when Frederick and Mary ascended the throne as King and Queen of Denmark

The Danish royal family were all smiles during King Frederick

Queen Consort Mary carried a series of family heirlooms with a fascinating history involving French Emperor Napoleon Bonaparte, and a heartwarming tribute to her mother-in-law, Queen Margrethe.

The royal couple's eldest daughter, Princess Isabella, 16, wore a pearl and diamond brooch gifted by Margrethe, who inherited it from her grandmother.

Meanwhile, King Frederick wore the insignia of Denmark's highest award, the Order of the Elephant, which will now be bestowed on all his children.

Maria carries her portrait of Queen Margrethe for the last time

Mary had a tribute to her mother-in-law, Queen Margrethe, pinned to her white dress, but it may be the last time she wears it.

Below her left collarbone she wore the Royal Family Order of Queen Margrethe II, or 'Ordensportrættet'.

The pendant is a portrait of the former queen, set in a frame of diamonds and pearls with a red and white ribbon.

The brooch is a personal decoration bestowed by the Queen at her discretion, rather than a state decoration.

Mary got the pin before her wedding to Frederik, but was first seen in public in 2012.

Queen Margrethe, Princess Benedict and their sister, Queen Anne Marie of Greece, all wear a similar badge with a portrait of their father.

But the sentimental brooch may soon be replaced by Frederik's Ordensportrættet.

The Australian-born royal will be the first and so far only recipient of Frederik's order, which will join a list of 200-year-old diamonds dating from 1829 and belonging to Empress Amélie of Leuchtenberg of Brazil.

What does Princess Isabella's brooch mean?

Mary and Frederik's eldest daughter, Princess Isabella, wore a small pearl brooch on her red Carolina Herrera shawl coat.

Isabella paired the designer coat with her mother's Valentino Black Leather Rockstud pumps, but it was her pin that was the most precious detail of her outfit.

The brooch contains a triangle of diamonds with a white pearl in the middle and a pink pear-shaped pendant.

It was reportedly given by Queen Margrethe to her eldest granddaughter in 2007, when she was just a baby, as a baptismal gift.

The beautiful brooch belonged to Queen Alexandrine of Denmark, who reigned from 1912 to 1947 and was Queen Margethe's grandmother.

Alexandrine wore the priceless brooch in a series of portraits in the early 20th century, before she became queen.

After her death in 1952, Margrethe inherited the brooch and wore it a few times before gifting it to Isabella.

Isabella only wore the pin publicly for the first time during her uncle Prince Joachim's 50th birthday dinner in 2019.

The last time she was seen wearing it was during her confirmation at Fredensborg Palace Church in 2022.

The history of Queen Mary's favorite ruby ​​jewelry

Queen Mary wore her chic dress, designed by Soeren Le Schmidt, with a sparkling array of red jewels representing the red and white Danish flag.

Mary added two hairpins, earrings and a brooch on her belt to her outfit that is part of the Ruby Parure, which also includes a tiara, necklace, ring and bracelet.

Le Schmidt said Vogue Scandinavia the white dress was the 'perfect backdrop' for the beautiful jewels and described the combination as 'very beautiful'.

“The colors of Denmark are red and white, so a graphically beautiful white dress decorated with the earrings and a brooch from the Ruby Set seemed like the right choice,” he said.

The tiara is made to look like a sparkling branch of diamond leaves with ruby ​​berries and has matching earrings that are customizable and which Mary has worn in a number of configurations in the past.

The set is a family heirloom originally ordered by Napoleon in 1804 for the late Queen of Sweden for his extravagant coronation.

They found their way into the Danish royal family when the daughter of the Swedish queen married the future King Frederick VIII in 1869 and have been in their hands ever since.

Mary has been the exclusive wearer of the rubies since her marriage to Prince Frederik in 2004, and last wore them at the palace's New Year's Eve dinner on January 1.

Three more children receive a new and very high order

King Frederik wore a blue sash with an elephant pendant on his right hip during the proclamation.

The pendant is the insignia of the Order of the Elephant, a Danish knighthood order and the country's highest award with origins dating back 600 years.

With the accession of King Frederik, Princess Isabella, Prince Vincent, 13, and Princess Josephine, 13, will also receive the commission.

Eldest sibling Prince Christian received the honor from Queen Margrethe on his 18th birthday last October.

The elephant emblem is worn at a number of special events and in two different configurations.

During the Order of the Elephant festival, royals wear the symbol on a gold chain hanging from each shoulder.

It is also worn as Frederik displayed it on Sunday, at the end of a blue sash on the right hip.

The Order of the Elephant has a complex and varied history dating back to the 14th century, during the reign of King Christian I.

Between 1580 and the present, 890 royals have been given the honor, with Margrethe commissioning 68 people during her 52-year reign.
