Russia’s Most Expensive Diamonds to Be Sold Online
A mining company has announced plans to sell a collection of what it says are the most valuable diamonds ever cut in Russia.
The largest in the collection is a 51.38-carat round cut diamond. It was produced by Russia's Alrosa company as part of a special collection called Dynasty.
The state-run Alrosa said the five-piece collection was named after the Romanov dynasty, which ruled Russia for 300 years. It is also meant to honor Russian ruler Peter the Great, who built the city of St. Petersburg. The company said Peter the Great started the country's first diamond factory early in the 18th century.
Alrosa calls the biggest piece "the purest of all large diamonds manufactured throughout Russian jewelry history." The 51.38-carat diamond is 2.5 centimeters in diameter.
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.
The project marked progress for Alrosa. The company is known for discovering rough diamonds, but not cutting and polishing them. It said the process "combined modern technologies with the secrets of jewelers of the Russian Imperial Court."
Russia is considered the largest diamond producer in the world. Alrosa and British-based diamond company De Beers produce about half of the world's rough diamonds.
Alrosa's president said at a launch event in Moscow that the collection is expected to go on sale as a set in an online auction in November.
The company expects to get at least $10 million for the diamonds, which are currently being shown in Moscow.
The collection will also travel to Israel, Hong Kong and the United States to give possible buyers the chance to get a close look.

这组钻石中最大的是一枚圆形切割钻，重51.38克拉 。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 。
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 。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 。该采矿公司指出，在18世纪早期，彼得大帝开创了俄罗斯第一家钻石厂 。
尔罗萨公司称最大的钻石为“俄罗斯珠宝史上所有大型钻石中最纯洁的” 。这块重51.38克拉的钻石直径为2.5厘米 。
“王朝”系列钻石出自2015年俄罗斯远东萨哈共和国发现的一块重179克拉的钻石原石 。公司团队耗时一年半才完成5块钻石的抛光工作 。
对尔罗萨公司而言，该项目标志着新阶段 。该公司以开采原钻著称，但从未涉足钻石切割和打磨领域 。据称，整个制作过程将“现代科技与俄罗斯宫廷珠宝打磨的秘诀合二为一” 。
俄罗斯是全球最大的钻石生产商 。尔罗萨公司和英属戴比尔斯钻石公司几乎开采了地球一半的钻石原石 。
