Coronation (1762)

Catherine was crowned at the Assumption Cathedral in Moscow on 22 September 1762. Her coronation marks the creation of one of the main treasures of the Romanov dynasty, the Imperial Crown of Russia, designed by Swiss-French court diamond jeweller Jérémie Pauzié. Inspired by Byzantine design, the crown was constructed of two half spheres, one gold and one silver, representing the Eastern and Western Roman Empires, divided by a foliate garland and fastened with a low hoop.

The crown contains 75 pearls and 4,936 Indian diamonds forming laurel and oak leaves, the symbols of power and strength, and is surmounted by a 398.62-carat ruby spinel that previously belonged to the Empress Elizabeth, and a diamond cross. The crown was produced in a record two months and weighed 2.3 kg (5.1 lbs). From 1762, the Great Imperial Crown was the coronation crown of all Romanov emperors until the monarchy's abolition in 1917. It is one of the main treasures of the Romanov dynasty and is now on display in the Moscow Kremlin Armoury Museum.
