Nicky Oppenheimer’s biography

Nicky Oppenheimer, born on June 8, 1945, is a South African billionaire and one of the most prominent figures in the diamond industry. He is the third-generation heir to the Oppenheimer family's fortune, which was primarily built through their control of De Beers, one of the world's leading diamond companies, and Anglo American, a multinational mining corporation. Oppenheimer was educated at Harrow School in the UK and later attended Christ Church, Oxford, where he earned a degree in Politics, Philosophy, and Economics.

In the late 1970s, Nicky joined the family business and rose through the ranks, eventually becoming Deputy Chairman of Anglo American and later Chairman of De Beers. Under his leadership, De Beers transformed from a mining-focused company into a more diversified business with a greater emphasis on branding and retail. In 2012, he made a historic decision to sell the family's 40% stake in De Beers to Anglo American for $5.1 billion, marking the end of the Oppenheimer family's century-long control of the diamond empire.

Despite stepping away from De Beers, Oppenheimer remains an influential figure in global business. He has since focused on managing his family's wealth through private investment firm Stockdale Street and has diversified into various industries, including agriculture, conservation, and venture capital. He is also deeply involved in philanthropic efforts, particularly in the areas of education, conservation, and community development in Africa.

How did Nicky Oppenheimer make money?
Nicky Oppenheimer's wealth stems from his family's control of De Beers, a diamond mining and trading company that dominated the global diamond industry for much of the 20th century. His business journey began when he joined the family business after completing his education. The Oppenheimer family initially gained control of De Beers through Ernest Oppenheimer, Nicky's grandfather, who became Chairman of the company in the 1920s. Over the decades, the family expanded their holdings and influence in the diamond industry, shaping the global market.

Nicky Oppenheimer played a crucial role in modernizing De Beers. During his tenure, he led initiatives to reform the company's diamond marketing practices and expand into retail branding. One of the most notable achievements under his leadership was the establishment of Forevermark, a diamond brand that guaranteed ethical sourcing and quality.

In 2012, Oppenheimer made a pivotal decision to sell the family's stake in De Beers for $5.1 billion to Anglo American, a company that the Oppenheimers also helped build. This sale marked the end of the family's direct involvement in the diamond industry. After the sale, Nicky shifted his focus to private investments through Stockdale Street and Tana Africa Capital, a joint venture investment firm that focuses on Africa.

Oppenheimer's portfolio has since diversified into sectors such as agriculture, conservation, and real estate. His family's involvement in conservation has been substantial, with large tracts of land in Botswana and South Africa preserved for wildlife through the Oppenheimer Generations Conservation Trust. His business philosophy has remained rooted in long-term sustainability and ethical business practices.
