The story is a classic example of traditional African culture in disagreement with contemporary justice.
The Diamonds explores the human misery and social meltdown caused by Sierra Leone's great diamond rush of the 1950s. Gibao Semabu, a successful peasant farmer, leaves his village for the Brave New World of diamond mining at Sewa. It is a totally different, corrupt world, where money is made quickly and then lost, theft is accepted, as long as one is not caught, and prostitution is very much a part of life. Initially timid but driven by an extraordinary ambition to get rich quick, Gibao succumbs to the greed and graft of the mines, and takes things further: he commits ritual murder after being told by a sorcerer that this will help him find large-size diamonds.
The Diamonds, on one level, is a parable of the destruction of peasant life by encroaching modernity - in the manner of Thomas Hardy, it juxtaposes the bucolic, beautifully ordered society of rural Sierra Leone with the graft-ridden, violent world of unregulated capitalism, showing how a clash between the two leads to the destruction of the former.
