© Paul Lowe / Panos Pictures..Lunda Norte, ANGOLA. 1992. Diamond Rush...Illegal diggers (known as camamgistas) working in the huge Catoba mine which stretches for two miles along the banks of the river Cuango. These miners are setting up small dams to dig gravel from the riverbed. Up to 5,000 miners are on site at any one time. The diggers work in teams of twenty, staking out their claim to a patch of land. One of them, who takes a double share of the profits, then sells the diamonds to one of the many dealers and smugglers...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.
