ALROSA unveils Russia’s 100 carat vivid yellow diamond called “New Sun”

Russia’s diamond mining company ALROSA has announced that it has completed the two-year cutting process of the country’s largest-ever diamond, a 100-carat vivid yellow stone named “New Sun”.                          

The New Sun was cut from a billion-year-old 200-carat rough diamond, which was unearthed from an ancient riverbed at the Udachnaya pipe mine in the Far East Republic of Sakha (Yakutia). ALROSA said 15 of Russia’s top jewelers worked meticulously to “achieve the perfect balance between light, color and the play of shades.

Thanks to the highest skill of Russian experts, the diamond has acquired impeccable proportions that accentuate its depth and brightness of its sunny hue. The cutting process marks a new stage in the development of the Russian Cut, a gem-cutting technique known for its precision and brilliance. New Sun is one of the most significant events in the gemstone industry in recent years, highlighting Russia’s high status in the global diamond industry.

ALROSA is the world’s largest diamond mining company by volume. It cut production by 2.8% to 34.6 million carats in 2023 and by 4.6% to 33 million carats in 2024. The company plans to produce 29 million carats of diamonds in 2025.
