How are natural Diamonds formed?

Diamonds are formed deep below the Earth’s surface, in the mantle, at depths of around
100 miles (160 kilometers) or more. They are created through a process called “diamond
formation,” which occurs when carbon atoms bond together under high pressure and high
temperature conditions.

It takes between 1 billion & 3.3 billion years for a natural Diamond to be formed in the Earth.
The conditions required for diamond formation are found only at great depths in the Earth,
and they are created by the intense heat and pressure that exists at those depths. The heat
and pressure cause the carbon atoms to bond together in a specific crystalline structure,
which results in the formation of diamond.

Diamonds are formed from carbon-rich materials that are subjected to
these high pressure and high temperature conditions over the course of billions of years.

The diamonds that we see and use today are usually brought to the surface of the Earth
through deep-source volcanic eruptions, which carry the diamonds from the mantle to the
surface.
