There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. [1] Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action. There is also at least one example of a heritage diamond mine (Crater of Diamonds State Park).

The economy of Botswana is currently one of the world's fastest growing economies, averaging about 5% per annum over the past decade. Growth in private sector employment averaged about 10% per annum during the first 30 years of the country's independence. After a period of stagnation at the turn of the 21st century, Botswana's economy registered strong levels of growth, with GDP growth exceeding 6–7% targets. Botswana has been praised by the African Development Bank for sustaining one of the world's longest economic booms. Economic growth since the late 1960s has been on par with some of Asia's largest economies. The government has consistently maintained budget surpluses and has extensive foreign-exchange reserves.

Yellowknife is the capital, largest community, and only city in the Northwest Territories, Canada. It is on the northern shore of Great Slave Lake, about 400 km (250 mi) south of the Arctic Circle, on the west side of Yellowknife Bay near the outlet of the Yellowknife River.
Crater Lake is a volcanic crater lake in south-central Oregon in the Western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a 2,148-foot-deep (655 m) caldera that was formed around 7,700 years ago by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks tenth for maximum depth, as well as third for mean (average) depth.
Blood diamonds are diamonds mined in a war zone and sold to finance an insurgency, an invading army's war efforts, terrorism, or a warlord's activity. The term is used to highlight the negative consequences of the diamond trade in certain areas, or to label an individual diamond as having come from such an area. Diamonds mined during the 20th–21st century civil wars in Angola, Ivory Coast, Sierra Leone, Liberia, Guinea, and Guinea-Bissau have been given the label. The term conflict resource refers to analogous situations involving other natural resources. Blood diamonds can also be smuggled by organized crime syndicates so that they could be sold on the black market.
The Orange River is a river in Southern Africa. It is the longest river in South Africa. With a total length of 2,432 km (1,511 mi), the Orange River Basin extends from Lesotho into South Africa and Namibia to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Lesotho and between South Africa and Namibia, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation and hydroelectric power. The river was named the Orange River in honour of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib, which is rendered in Afrikaans as Gariep River with the intrusion of a velar fricative in place of the alveolar click, Groote River or Senqu River, derived from ǂNū "Black". It is known in isiZulu as isAngqu.
Crater of Diamonds State Park is a 911-acre (369 ha) Arkansas state park in Pike County, Arkansas, in the United States. The park features a 37.5-acre (15.2-hectare) plowed field, one of the few diamond-bearing sites accessible to the public. Diamonds have been discovered in the field continuously since 1906, including the graded-perfect Strawn-Wagner Diamond, found in 1990, and the Uncle Sam, found in 1924, which at over 40 carats is the largest diamond ever found in the United States.
The Free State, formerly known as the Orange Free State, is a province of South Africa. Its capital is Bloemfontein, which is also South Africa's judicial capital. Its historical origins lie in the Boer republic called the Orange Free State and later the Orange Free State Province.
Southern Africa is the southernmost region of Africa. No definition is agreed upon, but some groupings include the United Nations geoscheme, the intergovernmental Southern African Development Community, and the physical geography definition based on the physical characteristics of the land.

The Ekati Diamond Mine, often simply called Ekati, is Canada's first surface and underground diamond mine and is owned by Burgundy Diamond Mines. It is located 310 km (190 mi) north-east of Yellowknife, Northwest Territories, and about 200 km (120 mi) south of the Arctic Circle, near Lac de Gras. Until 2014, Ekati was a joint venture between Dominion Diamond Mines (80%), Chuck Fipke, and Stewart Blusson, the two geologists who discovered kimberlite pipes north of Lac de Gras. Fipke and Blusson each held 10% stake in the mine, until Fipke sold his share to Dominion. In 2021, Arctic Canadian Diamond Company Ltd. acquired the Ekati Diamond Mine with associated assets and liabilities from Dominion Diamond Mines. In July 2023, Burgundy Diamond Mines purchased full control of Arctic Canadian Diamond Company.
An active volcano is a volcano that has erupted during the Holocene, is currently erupting, or has the potential to erupt in the future. A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. Volcanoes that will not erupt again are known as extinct volcanoes.
The Diavik Diamond Mine is a diamond mine in the North Slave Region of the Northwest Territories, Canada, about 300 km (190 mi) northeast of Yellowknife.
Lac de Gras is a lake approximately 300 kilometres (190 mi) north east of Yellowknife, in the Northwest Territories of Canada. Lac de Gras was the centre of the diamond rush of the 1990s. There are two working, and one closed, diamond mines in the area, Diavik Diamond Mine, Ekati Diamond Mine, and the care and maintenance Snap Lake Diamond Mine. It was called Ekati by aboriginal peoples.
Snap Lake Mine was a remote fly-in/fly-out operation located about 220 km (140 mi) northeast of Yellowknife, Northwest Territories, and, according to De Beers, was the first De Beers mine outside of Africa. It was also Canada's first completely underground diamond mine.
The Marange diamond fields are an area of widespread small-scale diamond production in Chiadzwa, Mutare District, Zimbabwe. 'Although estimates of the reserves contained in this area vary wildly, some have suggested that it could be home to one of the world's richest diamond deposits'. The hugely prolific fields are regarded by some experts as the world's biggest diamond find in more than a century. Production from Marange is controversial due to ongoing legal wrangles and government crackdowns on illegal miners and allegations of forced labour. In terms of carats produced, the Marange field is the largest diamond-producing project in the world, estimated to have produced 16.9 million carats in 2013, or 13% of global rough diamond supply. Marange is estimated to have produced 12 million carats in 2012, 8.7 million carats in 2011, and 8.2 million carats in 2010. While some diamond mines produce rough valued at over $1000 per carat, average production at Marange is estimated at under $50 per carat.
Child labour in the diamond industry is a widely reported and criticized issue on diamond industry for using child labour in diamond mines and polishing procedures in poor conditions mainly in India and Africa. In these mines, children come in contact with minerals, oil and machinery exhaust. In 1997, The International Confederation of Free Trade Unions claimed that child labour was prospering in the diamond industry in Western India, where the majority of the world's diamonds are cut and polished while workers are often paid only a fraction of 1% of the value of the stones they cut. It is argued that economic growth in Western India in the 1980s–90s was associated with an increase in the number of child workers who do simple, repetitive manual tasks that do not require long years of training or experience in low-paying hazardous working conditions that involve drudgery, and foreclose the option of school education for most of them.
The geology of Botswana plays a significant part in the country's economy. The basement rocks of the Kaapvaal-Zimbabwe craton extend into Botswana whilst in the east and southeast, metamorphic rocks of Archaean age are dominant. A younger cover of Karoo rocks and post-Cretaceous Kalahari Group sediments conceal the western margins of these older rocks and largely conceal Proterozoic orogenic belts too. This younger stratum was laid down in the Kalahari Basin underlying large parts of the centre of the country. In the northwest of Botswana, more recent sediments overlie rocks of Meso- and Neoproterozoic age rocks, belonging probably to the Damara Belt.
