The Mouawad Group has acquired the 51.38 carat Dynasty diamond, the largest and purest diamond in a collection of five stones offered for sale by Alrosa, a world leader in diamond mining. Alrosa unearthed the 179-carat rough diamond in 2015 at the Nyurbinskaya kimberlite pipe in the Russian Republic of Sakha (Yakutia).

The auction took place in August. The total Dynasty collection sold for $10 million making it the most expensive stone sold in the miner’s history. The impressive 51.38 carat Dynasty is a traditional round brilliant-cut diamond, D colour, VVS1 clarity, which also makes it the best quality large diamond ever manufactured in Russia.
