Elizabeth's crown was made of platinum and was set with the Koh-i-Noor diamond. Edward and Simpson married and became the Duke and Duchess of Windsor, but while Edward was a Royal Highness, George VI withheld the style from the Duchess, a decision that Elizabeth supported.

Elizabeth of Poland, Queen of Hungary beyond any other queen consort, and years before, Stephen II, Ban of Bosnia, married Elizabeth of Kuyavia, the daughter of the Duke Kazimierz III of Gniewkowo, Queen Elizabeth's cousin. Stephen II of Bosnia had a young daughter named Elizabeth, and after learning about her, the Hungarian queen insisted immediately on bringing her to the Hungarian court for fostering. Stephen was reluctant at first, but eventually dispatched Elizabeth. Three years later, Queen Elizabeth invited Stephen to Hungary and arranged a marriage between their children. The queen mother was heir to her brother Casimir's throne after the death of their sister, Cunigunde.
