In Zimbabwe, there has been a full ban on diamond exports while the country gets a clearance from the Kimberley Process.
The government said it imposed the ban while awaiting certification of gemstones from its controversial Marange fields.
Industry regulators are expected to quickly make a decision on the export of precious stones from Zimbabwe, which has been under a cloud since human rights groups charged that political cronies of President Robert Mugabe and the army had been profiting from illegal mining in Marange.
The government has accused Western countries of using the Kimberley Process Certification Scheme, which regulates the global diamond trade, to ban Zimbabwe from exploiting its own diamonds.
Harare has also rejected that diamonds for the Marange mine are blood diamonds, saying gems from the district have not funded armed conflict in the region.
