Zimbabwe’s state-controlled Herald newspaper reported on Thursday the Harare government is investigating De Beers over claims it smuggled out gems worth "hundreds of millions of dollars" from the controversial Chiadzwa fields.

Diamonds were found by villagers in Chiadzwa in 2006, leading to a frenzied diamond rush that was eventually crushed by the army. Zimbabwe's diamonds are the subject of an international ban although most industry watchers believe it is being widely flouted.
