Russian State-controlled diamond producer Alrosa sees strong global demand for diamonds in the first quarter of 2021 after its sales fell by 4% to 32.1-million carats in 2020 due to the coronavirus pandemic, it said on Thursday. Alrosa, the world's largest producer of rough diamonds, which competes with Anglo American unit De Beers, reduced 2020 production by 22% to 30 million carats as it suspended mining at less profitable mines.
