A Cartier bracelet with a sapphire from the Romanov collection was sold for about 411 million rubles.
The deal took place at a Sotheby's auction in Geneva, and the final price was more than double the upper limit of the estimate.
Ceylon sapphire weighing 197.8 carats was mined back in the 19th century. After the revolution, the stone ended up outside of Israel, and around 2015 it got a new life in a bracelet with diamonds and rock crystal from Cartier.
