Expert Arizona State University geoscience reveals potential locations considered factories diamond.
Sang-Heon Shim, a geoscientist from Arizona State University in the United States (USA), said that the border area between the Earth’s molten metal core and the Earth’s mantle could be a diamond factory.
Quoted SpaceIt was revealed after a new laboratory experiment, under extreme temperatures and pressures, a combination of iron, carbon and water.

Experts say any potential material found at the central boundary of the Earth’s mantle could form diamonds.
If this process also occurs deep inside the Earth’s core, it could explain some of the oddities, including why the Earth’s core contains more carbon than scientists think.
The findings also help explain the strange structure deep within the core-mantle boundary where earthquake waves slow dramatically.
This area, known as the “very low velocity zone”, is associated with strange mantle structures, including two giant plumes under the African and Pacific Oceans.
Nobody knows exactly what they are. Some scientists think they are 4.5 billion years old and are made of materials from very ancient Earth.
But new research suggests that some areas could be defined by the presence of plate tectonics, which likely began well after Earth’s formation.
“We’ve added a new idea that this isn’t a completely old facility,” Sang said Live science.
Under the pressure and temperature of the Earth, Shim says water behaves very differently than the Earth’s surface. The hydrogen molecules separate from the oxygen molecules due to the high pressure and the hydrogen is attracted to the iron which is the metal that makes up most of the core.
Therefore, due to the high pressure, hydrogen is attracted to iron, which is the metal that makes up most of the core.
When this happens, the hydrogen appears to get rid of the other light elements in the core, including the most important carbon.
According to Sang, carbon is expelled from the core and into the mantle. At the high pressures that exist from the core to the edge of the Earth’s mantle, the most stable form of carbon is diamond.
“This is the shape of a diamond,” Shim said.
However, the diamond found is not like the same diamond that could shine on a jewelry ring. Most of the diamonds that come to the surface of the Earth and end up becoming a person’s jewels are formed at a depth of several hundred kilometers, not several thousand kilometers.
