Scandinavian Royal Jewels (Documentary) 

For official royal events, Crown Princess Mary wears a historically rare ruby set that helps to tell Europe's history.
The rubies and diamonds were carried the first time by Napoleon's former wife, Désirée, to Napoleon's magnificent coronation in 1804.
Désirée takes the ruby set to Sweden and when her wealthy granddaughter, Louisa, marries Frederik VIII in 1869, "the Danish colors" will come to Denmark.
