the Kremlin Armoury and Diamond Fund in Moscow. Serbia . The Karađorđević crown jewels of Serbia were created in 1904 for the coronation of King Peter I. The pieces were made from material that included bronze of Karađorđe's cannon. This gesture was symbolic because 1904 was the 100th anniversary of the First Serbian Uprising.
