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.

The British Queen is seeking a multi-million-pound "pay rise" for the first time in 20 years to carry out her public role, a media report said. Buckingham Palace officials have demanded a seven -figure increase in the Civil List — the annual 7.9 million pounds which the Queen gets from the Parliament to maintain spending on state duties. The 7.9-million-pound grant covers the cost of the official royal household, from banquets and furnishings to housemaids and footmen. But, the Queen's official budget is estimated to be overspent by six million pounds a year. It is being covered by a 35-million-pound emergency reserve, expected to run out by 2012 — the Majesty's Diamond Jubilee Year. The civil list is negotiated every ten years and the Government has to report to Parliament on the grant by July 3 at the latest, the report said. Courtiers say the Queen should, at least, expect a hike to her annual funding which takes account of inflation over the past two decades. Prices have soared by 80 per cent in that time. The current level of the civil list was agreed by former prime minister John Major when he was chancellor of the exchequer in 1990, and frozen by Tony Blair in 2000. "The Queen has only been able to manage by very prudent financial management and by drawing on reserves," one royal courtier was quoted as saying. The monarchy costs more than 41.5 million pounds a year in public funds, excluding the cost of security. About 70 per cent of the 7.9 million pounds civil list expenditure goes on staff salaries. It also pays for official functions such as garden parties, receptions and entertainment.
