Yes, I am aware that Margrethe of Denmark celebrated her 40th year as Queen with a Ruby Jubilee gala at the Christiansborg palace about four months ago. But the display of tiaras was staggering. Let’s revisit! The guests flaunted their best baubles in honor of the woman some consider “the most intellectual monarch in Europe”. (Margrethe attended five universities, including Cambridge.) She was dressed in the full regalia of a member of the Danish Royal House, topped off with the iconic diamond-and-pearl Orange-Nassau Tiara. Congratulatoins, your majesty.
