Diamonds erupt to the surface of the earth at the top of the volcanic pipes that contain them.
Kimberlite pipes, the best source of mined diamonds today, erupt to the earth's surface like any volcano. You can read more about this morphology and volcanology, below.
No volcano produces diamonds. Diamonds are erupted to the surface of the earth through volcanic pipes, which look like upside-down volcanoes. These pipes erupt indicator minerals, some of which include diamonds.
Diamonds are brought to the surface in two main magma types with fairly extreme compositions. These are: Kimberlites and Lamproites. You can read more about them, below. Volcanic pipes that blast diamonds to the earth's surface, also erupt garnet xenoliths onto earth's surface. Only about one in every 200 such pipes contain diamonds. You can read more about the exploratory geology, below.
Natural diamonds are stones recovered from the area around volcanic pipes where diamonds erupt from below the earth's mantle.
Crater of Diamonds is the name of a state park in Arkansas that exists over geography fed by a volcanic pipe at some time during its history. Volcanic pipes erupt diamonds with other material to the surface of the earth from deep within the earth's mantle, where these materials are formed.
Via rising molten magma or by mining.
Diamonds are formed deep within the earth's mantle, under enormous pressure and extreme, high heat. Then, volcanic pipes erupt the diamonds to the earth's surface.
Diamonds are found at or near volcanic pipes that erupt them to the earth's surface. Be aware that Nigeria is not known for its diamonds.
Volcanic pipes that erupt diamonds to the earth's surface are uncommon in the United States. The Crater of Diamonds State Park in Arkansas is an exception.
Diamonds erupt to the earth's surface through volcanic pipes from deep within the earth's mantle where they are formed under great heat and pressure.
Diamonds are erupted to the Earth's surface from deep within the Earth's mantle through volcanic pipes. A volcanic pipe may exist in a rainforest: not all volcanic pipes that erupt diamonds to the Earth's surface exist in rainforests.
Diamond mining is only limited to the occurrence of the volcanic pipes that erupt diamonds to the surface of the earth.
Raw diamonds are mined from the earth around kimberlite pipes that erupt this material to the earth's surface.
Natural diamonds that erupt to the earth's surface were formed with the earth. Diamonds that come to earth from space may have been formed before earth: that research hasn't been documented to date.
Kimberlite pipes, the best source of mined diamonds today, erupt to the earth's surface like any volcano. You can read more about this morphology and volcanology, below.
No volcano produces diamonds. Diamonds are erupted to the surface of the earth through volcanic pipes, which look like upside-down volcanoes. These pipes erupt indicator minerals, some of which include diamonds.
Diamonds erupt to the surface of the earth by way of volcanic pipes, which bring not only diamonds, but other trace minerals to the surface. Over time, humans spot either diamonds or the trace minerals on the surface and determine ways to follow the 'trail' of materials to the volcanic pipe. Once the pipe is located, a diamond mine is established and the process proceeds to mine for diamonds. You can read the article, below, to learn more about how diamonds are taken from the ground.
