The court jeweller Ekart and Jérémie Pauzié made the Great Imperial Crown for the coronation of Catherine the Great in 1762. The beautiful crown reflects Pauzié's skilled workmanship. It is adorned with 4936 diamonds arranged in splendid patterns across the entire surface of the crown. Bordering the edges of the "mitre" are a number of fine, large white pearls. The crown is also decorated with one of the seven historic stones of the Russian Diamond Collection: a large precious red spinel weighing 398.72 carats (79.744 g), which was brought to Russia by Nicholas Spafary, the Russian envoy to China from 1675 to 1678. It is believed to be the second largest spinel in the world.
