Queen Mary was a regal vision on Friday evening as she arrived at Christiansborg Palace for a banquet to honour the state visit of Abdel Fattah Al Sisi, the President of the Arab Republic of Egypt.
King Frederik's wife, 52, was seen at the royal residence wearing the new Rose Stone tiara, she has just helped to redesign from jewels from the Danish royal family's collection.
Mary is the latest Danish royal to continue the tradition of reshaping crown jewels to suit the times, with the diamonds dating back to the 1840s and now set in a bandeau headpiece.
