Gem Diamonds Limited provided production of rough diamonds guidance for the year 2020. The lower than expected production of rough diamonds in 2020 may provide an opportunity for miners, such as De Beers and Alrosa, to release some of their stockpile inventory into the market, and a marked reduction in rough diamond supply, especially in the commercial diamond industry, is therefore unlikely in the short term. Total global rough diamond supply is estimated to decrease to approximately 110 million carats in 2020 compared to 141 million carats in 2019. This is largely due to a combination of planned mine closures, COVID-19 driven marginal mine closures, suspension and slowdown of certain operations and the cancellation of scheduled sales by De Beers and Alrosa. A number of mines have also been placed on prolonged care and maintenance until there is more certainty with regards to the impact of COVID-19 on continued operations and the diamond market.
