On 4 November 2011, Anglo American plc and CHL Holdings announced their agreement for Anglo American to acquire an incremental interest in De Beers, increasing Anglo American's 45% shareholding in the world's leading diamond company to 85%. De Beers plc was originally incorporated as De Beers Société Anonyme in 2000 in Luxembourg. Following the closure of this office, the company was reclassified as De Beers plc in 2017, with its head office now in Jersey. It is made up of two shareholdings: Anglo American plc has an 85% shareholding and the Government of the Republic of Botswana owns 15% directly. De Beers plc is the holding company of The De Beers Group of Companies. It is involved in many parts of the diamond value chain, from mining to sales, and is made up of a series of joint ventures and wholly owned operations.
