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.
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is a tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.

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 Argyle Diamond Mine was a diamond mine located in the East Kimberley region in the remote north of Western Australia. Argyle was at times the largest diamond producer in the world by volume, although the proportion of gem-quality diamonds was low. It was the only known significant source of pink and red diamonds, and additionally provided a large proportion of other naturally coloured diamonds, including champagne, cognac and rare blue diamonds.

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.

Golconda is a fortified citadel and ruined city located on the western outskirts of Hyderabad, Telangana, India. The fort was originally built by Kakatiya ruler Pratāparudra in the 11th century out of mud walls. It was ceded to the Bahmani Kings from Musunuri Nayakas during the reign of the Bahmani Sultan Mohammed Shah I, during the first Bahmani-Vijayanagar War. Following the death of Sultan Mahmood Shah, the Sultanate disintegrated and Sultan Quli, who had been appointed as the Governor of Hyderabad by the Bahmani Kings, fortified the city and made it the capital of the Golconda Sultanate. Because of the vicinity of diamond mines, especially Kollur Mine, Golconda flourished as a trade centre of large diamonds known as Golconda Diamonds. Golconda fort is currently abandoned and in ruins. The complex was put by UNESCO on its "tentative list" to become a World Heritage Site in 2014, with other forts in the region, under the name Monuments and Forts of the Deccan Sultanate.

It was called Ekati by aboriginal peoples.
The Mineral Revolution is a term used by historians to refer to the rapid industrialisation and economic changes which occurred in South Africa from the 1860s onwards. The Mineral Revolution was largely driven by the need to create a permanent workforce to work in the mining industry, and saw South Africa transformed from a patchwork of agrarian states to a unified, industrial nation. In political terms, the Mineral Revolution had a significant impact on diplomacy and military affairs. Finally, the policies and events of the Mineral Revolution had an increasingly negative impact on race relations in South Africa, and formed the basis of the apartheid system, which dominated South African society for a century. The Mineral Revolution was caused by the discovery of diamonds in Kimberly in 1867 and also by the discovery of gold in Witwatersrand in 1886. The mineral mining revolution laid the foundations of racial segregation and the control of white South Africans over black South Africans. The Mineral Revolution changed South Africa from being an agricultural society to becoming the largest gold producing country in the world.

Ghana is also a major producer of bauxite, manganese and diamonds. Ghana has 20 large-scale mining companies producing gold, diamonds, bauxite and manganese; over 300 registered small scale mining groups; and 90 mine support service companies. Other mineral commodities produced in the country are natural gas, petroleum, salt, and silver.
Tanzania is a land rich in minerals. Mining makes up more than 50% of the country's total exports, of which a large part comes from gold. The country has gold reserves of 10 million ounces, generating revenue of over a billion USD. Diamonds are also found in significant amounts. Since it was opened in 1940, the Williamson diamond mine has produced 19 million carats (3,800 kg) of diamonds. Gemstones, nickel, copper, uranium, kaolin, titanium, cobalt and platinum are also mined in Tanzania. Illegal mining and corruption are ongoing problems. In 2017, the government passed a series of bills aimed at increasing revenue from minerals after a scandal which caused the dismissal of the Minister for Energy and Minerals.
