Imperial crown of Russia

The Imperial crown of Russia (Russian: Императорская Корона России), also known as the great imperial crown (Russian: Великая Императорская Корона), was used for the coronation of the monarchs of Russia from 1762 until the Russian monarchy's abolition in 1917. The great imperial crown was first used in the coronation by Catherine the Great, and it was last worn at the coronation of Nicholas II. It was displayed prominently next to Nicholas II on a cushion at the State Opening of the Russian Duma inside the Winter Palace in St. Petersburg in 1906. It survived the 1917 revolution and ensuing civil war and is currently on display in Moscow at the Kremlin Armoury's State Diamond Fund.
