A mining company has announced plans to sell a collection of what it says are the most valuable diamonds ever cut in Russia.
一家采矿公司称，打算出售俄罗斯有史以来价值最高的一组钻石。
The largest in the collection is a 51.38-carat round cut diamond.
这组钻石中最大的是一枚圆形切割钻，重51.38克拉。
It was produced by Russia’s Alrosa company as part of a special collection called Dynasty.
这枚钻石由俄罗斯尔罗萨公司切割打磨，系“王朝”特别系列钻石之一。
The state-run Alrosa said the five-piece collection was named after the Romanov dynasty, which ruled Russia for 300 years.
尔罗萨是国营企业，该公司表示，这组钻石（5枚）系列用曾统治俄罗斯300年的罗曼诺夫王朝来命名。
It is also meant to honor Russian ruler Peter the Great, who built the city of St. Petersburg.
该钻石系列也是对建造圣彼得堡市的统治者彼得大帝的纪念。
The company said Peter the Great started the country’s first diamond factory early in the 18th century.

The Dynasty collection was created from one 179-carat rough diamond discovered in 2015 in Russia’s far eastern republic of Sakha.

It took a team more than a year and a half to complete the five polished diamonds.
