The King's Mother's Jewels Are Going to Auction — Why?

In November 2026, some of the most personal jewels of Sweden's royal family are heading to auction. Among them is a striking sapphire necklace once worn by Princess Sibylla — the mother of King Carl XVI Gustaf — and later by her daughter, Princess Birgitta.
Now, nearly two years after Birgitta's death, her heirs are offering these family treasures for sale. Swedish commentators have questioned the decision, and reports suggest the King may not be pleased.
But why would the family part with jewels that have accompanied generations of royal women? And what makes this particular collection so difficult to see leave the family?
