The World Diamond Council’s (WDC’s) revised System of Warranties (SoW) is set to reach its first critical deadline on September 21, when it becomes obligatory for all rough diamond sales. “We strongly urge all companies, but especially . . . rough diamond traders, to transition to the revised SoW, if they have not done so yet, to be ready for the September 21 deadline,” WDC executive director Elodie Daguzan said on April 24.
