1. Princess Ragnhild of Norway It is usually said, that her jewellery from her mother will be returned to the RF. That would refer to Queen Maud’s diamond tiara. The Boucheron pearl tiara was a gift from her godmother, and as her personal possession would pass to her children. Princess Ragnhild only died a comparatively short time ago. I believe that the RF will let more time pass before they wear the jewels associated with Princess Ragnhild.
2. Countess Ruth of Rosenborg Her daughter-in-law Countess Jutta has often worn the turquoise star tiara, and at least once she also wore the garnet kokoshnik. I guess that she will continue to wear the star tiara. Afaik, none of the siblings attended the 40th jubilee this year, so they didn’t have occasion to wear tiaras after Countess Ruth’s death. But maybe next year for Prince Henrik’s 80th birthday? I have no idea about the other tiaras in that branch of the family. The opal tiara and the lava parure haven’t been seen for years.
3. Countess Dorrit of Rosenberg She was seen several times with a diamond tiara at galas. I have once read that she borrowed this tiara, but I do not know if that is a reliable information
