We should first mention that diamonds are not made of carbon. The notion that they are created from carbon is wrong. This is confirmed by the fact that carbon appeared much later after the creation of diamonds. Carbon is created by plants that will be flattened by soil mass. But the origins of diamonds date back 4,600 million years to 600 million years ago. But plants began to appear 45 million years ago.
Diamonds form in the Earth’s mantle and reach close to its surface due to volcanic eruptions. When these explosions occur, the Earth’s magma moves very fast from very deep to its surface. Of course, in order to find the diamond, mining is needed for it and mines are built for this purpose (https://idol-man.blog/%ce%b3%ce%b5%cf%89%ce%b3%cf%81%ce % b1% cf% 86% ce% b9% ce% b1-% cf% 84% ce% bf-% ce% bc% ce% b5% ce% b3% ce% b1% ce% bb% cf% 85% cf % 84% ce% b5% cf% 81% ce% bf-% ce% bf% cf% 81% cf% 85% cf% 87% ce% b5% ce% b9% ce% bf-% cf% 83% cf % 84% ce% bf% ce% bd /).
Diamond is created when high temperature, above 1000 degrees Celsius and high pressure coexist. This pressure can exist at depths beyond 150 km. This combination of temperature and pressure exists in specific areas within the Earth’s mass.
Another way diamonds are created is when asteroids drop on the Earth’s surface. As the asteroid hits the Earth’s surface, there is enormous pressure as well as temperature, which favors the formation of a diamond. That’s why there are usually diamonds around craters of this kind.
