Russian diamond producer Alrosa has announced the discovery of a 468-carat diamond, which it claims is the largest gemstone-quality rough in the country’s history.
The diamond, described as amber in colour, was unearthed in an Alrosa mine in the Yakutia region. The previous record was a 401-carat rough discovered in 2013.
Alrosa recently showcased the New Sun, a 100-carat fancy vivid yellow diamond said to be the largest of its kind in Russia. CEO Pavel Marinychev said that 2025 had been a significant year for the Russian diamond industry so far.
“In April, we presented the largest diamond ever cut in our country. And this year, nature gave us such an incredible find,” Marinychev said.
“It is symbolic that it was found in the year of the 80th anniversary of the Great Victory. Therefore, we decided to name it in honour of such a significant event for our entire country.”
As reported by Rapaport News, Alrosa recently reported a 42 per cent decline in revenue during the first quarter of this year.
