How Did the Oppenheimer Family Build Its Diamond Empire?

Nicky Oppenheimer's grandfather, Ernest Oppenheimer, was a German-born Jewish diamond merchant who emigrated to South Africa in 1902 and founded Anglo American Corporation in 1917 to mine the Witwatersrand gold fields near Johannesburg. In 1929 he took control of De Beers Consolidated Mines, transforming it from Cecil Rhodes's original diamond concern into a company that at its peak controlled more than 85 percent of the world's rough diamond supply. Nicky's father, Harry Oppenheimer, led both Anglo American and De Beers through much of the twentieth century.

Nicky Oppenheimer joined the family businesses and became deputy chairman of De Beers Consolidated Mines and chairman of its Diamond Trading Company subsidiary in 1985, before becoming chairman of the full De Beers Group in 1998, a position he held for 14 years.

Why Did Nicky Oppenheimer Sell the Family's Stake in De Beers?

In 2012 Oppenheimer orchestrated the sale of the family's remaining 40 percent stake in De Beers to Anglo American for approximately 5.1 billion dollars in cash, concluding 85 years of Oppenheimer family control over the diamond giant. The sale came as De Beers navigated market fluctuations and the emergence of synthetic diamonds. Since then Oppenheimer has redeployed his capital into private equity investments across Africa, Asia, the United States and Europe through Stockdale Street and Tana Africa Capital, and into large-scale conservation land holdings across southern Africa.
