A brief annotation
For the coronation of the Empress Catherine II in 1762, the court jeweler Georg Friedrich Eckardt and a jewelry master Jérémie Pauzié created the Great Imperial Crown. The crown of the Russian Empire is decorated with 4,936 diamonds and the most famous of its jewels is a spinel ruby of 398.72 carats. This stone was purchased in 1676 from the Chinese Emperor Kangxi and originally decorated the imperial headdress of Elizabeth I. For a long time the precious stone was taken for a huge ruby, and only at the end of the last century gemologists proved that the stone was a spinel.
