Diamond-producing countries on the African continent received about $8.1-billion in 2018, or 9.5% of the $85.9-billion worth of revenues generated from the sale of diamond jewellery, and some still may consider that an insufficient share, World Diamond Council (WDC) president Stephane Fischler told delegates attending the Russia-Africa Summit in Sochi, Russia, earlier this week. He stressed that the economic potential of the diamond resource, whose value increased by about a factor of five as it travelled from the mine to the countertop of the retail jeweller, was indisputable.
