Diamond producer Debswana aims to increase output by 38% this year to pre-pandemic levels of 23-million carats, a company official said on Friday, as the global diamond market recovers with the easing of travel restrictions and jewellers reopen. Jointly owned by Anglo American unit De Beers and the Botswana government, Debswana cut production by 29% to 16.6-million carats in 2020 as the Covid-19 pandemic hurt demand and global travel restrictions affected trading.
