The then Crown Princess Sonja wore the same jewels as she did for the dinner in Oslo last week.
Queen Josephine's Diamond Tiara etc.
Crown Princess Sonja then wore her emeralds for the ball before the wedding of the Prince and Princess of Wales in 1981.
There have been glittering Balls ahead of the weddings of most members of the British Royal Family up until the 1980s! Though usually private, with few pictures, I've found a picture of the now King Juan Carlos and Queen Sofia of Spain arriving at Princess Anne's Wedding Ball in 1973! Are there any pictures of other guests? or reports about the Tiaras?
What about the wedding balls of other members of the Royal Family??
These are some of the Foreign Royal Guests that attended the wedding, and were probably at the Ball the previous evening as well!
