The message hidden in Queen Mary of Denmark’s stunning outfit that almost no one noticed

Queen Mary of Denmark hid a touching message in an easy-to-miss detail on her outfit during a state visit to Sweden.

The Australian-born royal donned a stunning brooch with Swedish and Danish roots as he attended a day of formalities in Stockholm.

Mary received the brooch from her mother-in-law, Queen Margrethe, after the birth of her eldest child, Prince Christian, 18, who was unable to visit his parents.

The sparkling brooch has been passed down from generation to generation since Margrethe received it from her mother, Queen Ingrid, who was born in Sweden.

Queen Ingrid inherited the inheritance from her mother, Crown Princess Margareta of Sweden.
