$ 20m replica of Great Imperial Crown on Display

Russian diamond mining company Alrosa highlights the International Diamond Week in Israel (IDWI) to be held between February 13 – 15, 2017. Star attraction at the Alrosa’s stalls will be the display of a replica of the Great Imperial Crown of the Russian Empire, which was used in the coronations of all Russian monarchs since the coronation of Catherine the Great in 1762.

The centerpiece of the crown is a red spinel weighing 398.72 carats, one of the seven historic stones of the Russian Diamond Collection. The spinel in the original is replaced by a natural rubellite (red tourmaline) weighing approximately 400 carats.

The creation of the replica took two months of painstaking work by more than 60 master-jewellers, using 3D Printer technology.
