The potential sale of De Beers's London HQ offers a rare glimpse inside the mining giant, from subterranean vaults to a rooftop helipad.
Number 17 Charterhouse Street, a fortress in the heart of London, has been De Beers’s headquarters since 1979, but the street has been its home since the 1930s. At its peak 90 percent of the world’s diamonds passed through this structure. That’s now coming to an end. De Beers’s owner, Anglo American Plc, is leaving the building and moving staff across the capital as part of a wider cost-cutting plan.
