In the Democratic Republic of Congo, almost all diamond mining is done by hand. It’s a labor-intensive process that requires hauling away layers of dirt and rock, sometimes 50 feet deep, to expose ancient beds of gravel where the crystals are found. Miners then wash and sift that gravel one shovelful at a time in search of tiny glints of light that might be a diamond.
If they are lucky, a peppercorn-size crystal could fetch them a few dollars, once the mine owner gets his take. In New York’s diamond district such a gem, cut and polished, would be worth several hundred dollars.
Lynsey Addario and I journeyed to the heart of Congo’s diamond mining district in August to report on an $81.4 billion industry that links the miners of Tshikapa with the glittering salesrooms of the world’s jewelry retailers.
It was an arduous trip, one that required an internal flight on an airline that has been blacklisted by the European Union for its shaky safety record, followed by long 4×4 drives on red dirt tracks down to the mining sites.
