Happy Birthday to Countess Madeleine Kogevinas née Bernadotte, who turns 80 today! The only daughter of Prince Carl Bernadotte and Countess Elsa von Rosen, she was the niece of Queen Astrid of Belgium, Crown Princess Martha of Norway, and Princess Margaretha of Sweden and Denmark, and is the first cousin of King Harald V of Norway, King Baudouin of Belgium, King Albert II of Belgium, and Grand Duchess Joséphine Charlotte of Luxembourg. To mark the occasion, we are taking a look at her Pearl and Diamond Floral Tiara.

The Pearl and Diamond Floral Tiara was first worn by Countess Elsa von Rosen, and reportedly originates from her family, rather than a gift from her mother-in-law, Princess Ingeborg of Sweden, who gave most of her jewels to her daughters, rather than her only son, Prince Carl, who married morganatically. Countess Elsa notably wore the Tiara at King Gustav V of Sweden’s 80th Birthday in 1938.

After Countess Elsa’s death in 1991, the Tiara was inherited by her only daughter, Countess Madeleine, who loaned the Tiara to her step-mother, Princess Kristine Bernadotte, for Crown Prince Haakon of Norway’s 18th Birthday Gala that year.

However, the Tiara is usually worn by Countess Madeleine, who has worn it to almost all of the royal events she still attends, including the Wedding of Crown Prince Haakon of Norway, the Wedding of Princess Märtha Louise of Norway, the Wedding of Crown Princess Victoria, and most recently, King Harald and Queen Sonja’s 80th Birthday Banquet.

However, the Tiara is not the only major heirloom worn by Countess Madeleine, who also owns a sapphire demi-parure, which she wore at King Harald’s 40th Birthday in 1977 and has also been worn by her daughters, as well as a gold tiara which was worn by Countess Madeleine at Crown Prince Haakon’s 18th Birthday Gala and her daughter at King Harald and Queen Sonja’s 80th Birthday Banquet.
