The most expensive diamond ever polished in Russia, named Dynasty after the Romanov-era Imperial Court, failed to sell in an auction.

Alrosa PJSC said it didn’t receive a high enough offer for the 51.4-carat gem in a Nov. 29 online auction. The stone has the best so-called triple excellence cutting quality, a characteristic Alrosa says is shared by less than 1 percent of all gems ever cut.
