Russian State-controlled diamond producer Alrosa said on Friday its 2018 net profit rose 15% to 90.4 billion roubles, as a fall in sales volume was offset by stronger global prices.
Though sales volume fell by 8% year-on-year, stronger pricing, particularly in the first half of 2018, meant sales by value increased by 6% to $4.4-billion, Alrosa said.
