Princess Isabella of Denmark is marking a major royal milestone for her 18th birthday. The second child of King Frederik and Queen Mary celebrated her big day on Monday, April 21—and her first-ever tiara is an especially meaningful one.
The princess wore an elegant orange gown for her official birthday portraits, with the Danish royal family releasing three different photos to celebrate the occasion. As is tradition, she received her first tiara as an 18th birthday gift, and the stunning turquoise piece she debuted in the photos has a sweet tie to her grandmother, Queen Margrethe.
