Yvonne, a Zairean diamond dealer, shows off his gold rings. He claims to turn over 1,300 carats of diamonds every day, worth $250,000 at European prices. Many dealers come from neighbouring Congo, selling the illegal diamonds in Luanda, Kinshasa and even Antwerp, Belgium. Angola is the world's fourth largest diamond producer, generating $650m a year, although illegal mining and smuggling significantly distort the figures. With the country embroiled in civil war for almost the entire period since independence in 1975, much of the diamond production has been in the hands of the UNITA rebels.
