101 carat diamond to be auctioned in Geneva jewellery sale

GENEVA: The largest diamond ever cut in Russia - a 100.94 carat stone called the Alrosa Spectacle - will be auctioned in Geneva later this month.

The diamond could fetch between 12 and 18 million Swiss francs ($19.96 million) when it goes under the hammer at Christie's on May 12. "This fantastic 100 carat D color diamond was cut from a rough stone that originally weighed more than 200 carats. It was called the Sergei Diaghilev rough diamond and it was mined in 2016," Marie-Cecile Cisamolo, a specialist in the auction house's jewellery department, said.
