Petra Diamonds

Petra Diamonds is a leading independent diamond mining company focused on the production of rough diamonds from open-pit and underground operations. The company is headquartered in Jersey, Channel Islands, and operates primarily in South Africa and Tanzania. Petra Diamonds is listed on the London Stock Exchange and the Johannesburg Stock Exchange. Its core assets include the Cullinan, Finsch and Koffiefontein mines in South Africa, as well as the Williamson mine in Tanzania. The Cullinan mine is particularly notable as the source of some of the world's most famous large diamonds, including the 3 106-carat Cullinan Diamond discovered in 1905. Petra Diamonds produces a range of diamond sizes and qualities, from industrial-grade stones to high-value gem-quality diamonds. The company employs several thousand people across its operations and has a significant economic footprint in the regions where it operates. Petra Diamonds has faced financial challenges in recent years, including debt restructuring and operational optimisation efforts. The company was founded in 1997 and has grown through acquisitions and the development of historic mining assets, establishing itself as a significant player in the global diamond industry.
