Are most most diamonds formed inside kimberlite?
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
Can diamonds be found underground?
Yes, diamonds are typically found underground in the Earth's mantle, at depths of around 150-200 kilometers. They are brought to the surface through volcanic eruptions in a type of rock called kimberlite pipes.
Where is kimberlite found?
Kimberlite is typically found in regions with ancient volcanic activity, such as cratons and continental lithosphere. Some common locations include southern Africa, Canada, Australia, and Russia. These regions have preserved the deep mantle source rocks that give rise to kimberlite.
What is the source of most of the diamonds that are used for industrial purposes?
Most industrial diamonds are synthetic, created in laboratories rather than being mined from the earth. These synthetic diamonds are specifically designed for industrial applications due to their hardness and durability.
Where are diamonds found most?
Diamonds are most commonly found in Africa, particularly in countries like Botswana, South Africa, and Angola. Other significant sources of diamonds include Australia, Russia, and Canada. These countries are known for their rich diamond deposits and large-scale mining operations.

What are brown diamonds?
Brown diamonds are the most common colour of diamonds mined, of gem-quality. Only about 20% of all diamonds mined are of gem quality.
What rock would most likely contain diamonds?
Indicator minerals for diamond include kimberlite and lamproite.
What is a craton and what is a kimberlite pipe and how are they linked to the discovery of the diamond?
A craton is 'an old and stable part of the lithosphere' -- the earth's crust. One class of inclusions in the formation of the earth's crust when subductions of crust were folded into the deep, kimberlite diamond areas that lie about 150-450 K below the surface. Diamonds as we know them are exploded to the earth's surface through kimberlite pipes, which are carrot shaped and widest at the surface. Although not all kimberlite pipes are sources for diamonds, most diamonds are found in areas where kimberlite pipes occur.
What cities are diamonds found?
You can purchase diamonds in most any city in the world. There is no 'city' where diamonds are mined, however.
How do kimberlite pipes and diamonds form?
Kimberlite pipes form when magma rises from deep within the Earth's mantle and rapidly reaches the surface, carrying diamonds and other minerals with it. The extreme pressure and temperature inside the mantle crystalize carbon atoms into diamonds within the kimberlite magma. When the kimberlite erupts onto the surface, it brings diamonds along, creating diamond deposits.
Where is kimberlite found?
Kimberlite is typically found in regions with ancient volcanic activity, such as cratons and continental lithosphere. Some common locations include southern Africa, Canada, Australia, and Russia. These regions have preserved the deep mantle source rocks that give rise to kimberlite.
Does America buy the most diamonds mined in the world?
Probably not, because 80% of all diamonds mined are industrial diamonds. Every civilized country purchases industrial diamonds. Consumers in the United States, however, purchase about 50% of all gem-quality diamonds mined, according to the World Diamond Council.
Where do most industrial diamonds come from?
Industrial diamonds come from diamond mines, in fact about 75% of all diamonds mined are industrial diamonds.
Why are diamonds most commonly found in Africa?
Diamonds are most commonly found in Africa due to the presence of ancient volcanic activity that brought diamonds closer to the Earth's surface where they could be mined. Additionally, Africa has a long history of diamond mining, with countries like Botswana, South Africa, and Angola having significant diamond deposits. Political stability and the presence of well-established diamond mining operations also contribute to Africa's status as a major diamond producer.
Do all volcanoes have kimberlite?
No, not all volcanoes have kimberlite. Kimberlite is a type of volcanic rock that often contains diamonds, but it is only found in specific geological settings. Other types of volcanoes can be composed of different types of magma and erupt different types of rocks.
