Diamonds form about 100 miles (161 km) below the Earth's surface, in the molten rock of the Earth's mantle, which provides the right amounts of pressure and heat to transform carbon into diamond. In order for a diamond to be created, carbon must be placed under at least 435,113 pounds per square inch (psi or 30 kilobars) of pressure at a temperature of at least 752 degrees Fahrenheit (400 Celsius).

What layer do diamonds form in the Earth?
The vast majority of diamonds form within the Earth's lithospheric mantle at depths of around 150 to 190 km. Volcanic pipes bring them to the surface with kimberlite or lamproite in the pipes. Diamonds are formed from carbon.
How are industrial diamonds formed?
Industrial diamonds are typically formed under very high pressure and temperature conditions in the Earth's mantle. They are formed when carbon atoms are subjected to these extreme conditions and transform into diamond crystals. These diamonds are then brought to the surface through volcanic eruptions.
What layer of the earth do you get diamonds?
Diamonds are typically formed in the Earth's mantle layer, which lies between the outer crust and the inner core. They form under tremendous pressure and high temperatures in the mantle's depths before being brought to the surface through volcanic eruptions or other geological processes.
What of earths layer is formed by diamond?
Diamonds are typically formed in the Earth's mantle, which is the layer located between the crust and the core. They are formed under high pressure and temperature conditions deep within the mantle, around 150-200 kilometers below the surface. Through processes involving carbon atoms being subjected to extreme heat and pressure, diamonds gradually form over millions of years.
What does epithermal mean?
"Epithermal" refers to a type of hydrothermal mineral deposit formed at relatively shallow depths and moderate temperatures, typically between 50-200 degrees Celsius. These deposits are often associated with hot springs and can contain valuable minerals like gold and silver.
Which of the earths layer are diamond formed?
Diamonds are usually formed in the mantle.
Can diamond form inside a volcano?
No. As the pressure at the relatively shallow depths where volcanoes occur is not high enough to form diamonds. However it is true that volcanic eruptions can cause diamonds to be erupted onto the surface but these diamonds were already formed at much greater depth.
Why do diamonds form in kimberlite?
Diamonds are formed deep within the earth's mantle. Diamonds don't 'form' in kimberlite; kimberlite rocks are solidified remnants of a specific type of nearly supersonic volcanic eruption of molten material derived from depths of up to 500 km. The igneous rock thus formed consists of igneous rock from depths far greater than normal volcanic eruptions, and include exotic minerals such as diamonds which form at depths greater than 100 km. You can read more about kimberlite, below.
How do caol and diamond differ?
Raw materials for coal and diamonds are the same. Buried dead plant material begins the process to coal. But the process for creating diamonds requires enormous pressures, so diamonds are formed at extreme depths (over 90 miles underground). Volcanos bring the diamonds to the surface or at least to depths where mining is practical. See: http://en.wikipedia.org/wiki/Diamond
How did diamonds arrive on the earths surface?
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.
What igneous rock are diamonds formed from?
Diamonds are formed from carbon.
Where do you get diamonds from?
Diamonds come from diamond mines. As a mineral, the stones are formed "...at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth's mantle," according to Wikipedia.Read more, below.
How are laboratory diamonds minerals?
Diamonds formed from carbon in the lab, are diamonds formed from the mineral carbon.
What is formed by heat and pressure in the earths crust?
Many elements and materials which could not have been produced any other way (like diamonds).
What layer do diamonds form in the Earth?
The vast majority of diamonds form within the Earth's lithospheric mantle at depths of around 150 to 190 km. Volcanic pipes bring them to the surface with kimberlite or lamproite in the pipes. Diamonds are formed from carbon.
Are diamonds sulfides?
No. Diamonds are formed from carbon.
How much pressure and heat is required for diamond formation?
Natural diamonds are formed deep within the earth's mantle. According to Wikipedia: "These depths are estimated between 140 and 190 km though occasionally diamonds have crystallized at depths about 300 km as well. The rate at which temperature changes with increasing depth into the Earth varies greatly in different parts of the Earth." Read more, below.
