De Beers Group is an international corporation that specialises in diamond mining, diamond exploitation, diamond retail, diamond trading and industrial diamond manufacturing sectors. The company is currently active in open-pit, large-scale alluvial, coastal and deep sea mining. It operates in 35 countries and mining takes place in Botswana, Namibia, South Africa, Canada and Australia. From its inception in 1888 until the start of the 21st century, De Beers controlled 80% to 85% of rough diamond distribution and is a monopoly. Competition has since dismantled the complete monopoly, though the De Beers Group still sells approximately 29.5% of the world's rough diamond production by value through its global sightholder and auction sales businesses, an effectual monopoly, as this still allows it to control prices, inflating them dramatically. By volume, De Beers has slipped to the second largest producer with a market share of 22.3%, trailing Russian diamond miner ALROSA.
The Cullinan Diamond was the largest gem-quality rough diamond ever found, weighing 3,106.75 carats (621.35 g), discovered at the Premier No.2 mine in Cullinan, South Africa, on 26 January 1905. It was named after Thomas Cullinan, the mine's chairman. In April 1905, it was put on sale in London, but despite considerable interest, it was still unsold after two years. In 1907, the Transvaal Colony government bought the Cullinan and then presented it to Edward VII, King of the United Kingdom, who had it cut by Joseph Asscher & Co. in Amsterdam.
Cullinan is a small town in the Gauteng province of South Africa. It is located 30 km (19 mi) east of the city of Pretoria along the diamond route and is heavily reliant on tourism and the mine that dominates the skyline. The town is named after diamond magnate Sir Thomas Cullinan.
