When Princess Birgitta died in December 2024, she left behind a large collection of jewellery.
Some of it will be auctioned at Sotheby's in Geneva on Wednesday, as Svensk Damtidning was the first to report.
Among the items up for sale is a sapphire and diamond necklace with matching earrings.
The set was originally a wedding gift to her mother, Princess Sibylla, and was inherited by Princess Birgitta. Sotheby's values it at between 300,000 and 500,000 Swiss francs, equivalent to 3.6 to 6 million Swedish kronor.
Other valuables being auctioned include a pearl necklace given to the princess by Prince Bertil as a christening gift, and a brooch featuring a padparadscha sapphire surrounded by diamonds.
