The crown was made for King Sigismund II Augustus. After King's death it was pawned to Giovanni Tudesco and later ransomed by King Sigismund III Vasa for 20,000 florins and used for his coronation in Uppsala as the King of Sweden on February 19, 1594.
The appearance of the crown was a type of corona clausa, consisting of five larger and five smaller parts (portiones maiores quinque, minores quinque) and 262 precious stones, including 24 emeralds, 64 rubies, 30 sapphires, 21 diamonds and 123 pearls. In the 18th century the crown was depicted in the portrait of Sigismund I the Old by Marcello Bacciarelli, painted to embellish the Marble Room at the Royal Castle in Warsaw.
