Queen Sophie Magdalene’s will of 1746 decreed that her jewelry was not to be given to one person, but always to be “with the crown”.
The Crown Jewels of Rosenborg consist of four set of jewels, mounted with pearls, rubies, emeralds, rose and brilliant cut diamonds. They may one be used by The Queen and only within Denmark. They are used a couple of times a year, one being at the New Year Banquet.
The numbers on the photos coincide with the website that explains each piece in detail.
