You can read more about the results of the high-pressure, high temperature processes used on diamonds, below.
The exact process, however, is proprietary.

Why can't we make diamonds?
We -- humans -- can manufacture diamonds. It takes enormous heat and pressure to produce man-made diamonds.
Are chocolate diamonds formed under high pressure?
All diamonds are formed under high pressure - - and high heat.
How can the effect on heat on a reaction be determined?
heat is treated as a reactant or product
Is diamonds from carbon using heat and pressure are made of glass?
Diamonds are formed from carbon, as you state; glass is formed from silica. The two are not related, except that some glass and some diamonds appear similarly.
How does carbon change into diamonds?
Diamonds are formed deep underground inside the earth's mantle, under intense pressure and extreme heat. You can read more, below.
What does heat treated black diamond mean and natural?
Heat treating any diamond may enhance it, but also devalues it. Heat treating natural diamonds is common, and may include black diamonds. You can read more about the process of heat treating diamonds, below.
Are diamonds manipulated in any way?
Some diamonds can be enhanced by heat or other techniques, to make their colour more vibrant, or to hide visible flaws. Any enhanced diamond is quickly obvious to any certified gemologist, and as well, enhanced diamonds are less valuable/ expensive than diamonds that have not been treated.
Which tretment can remove some or all color form certain types of light brown diamonds?
There is apparently a high-pressure, high heat process that can alter a brown diamond's colour. This treatment can 'heal' lattice defects that cause the brown colour. Note, however, that treated diamonds are less valuable that natural diamonds. A GIA certified gemologist will always be able to tell that a diamond has been treated.
Why can't we make diamonds?
We -- humans -- can manufacture diamonds. It takes enormous heat and pressure to produce man-made diamonds.
What material is made out of heat and pressure?
diamonds
Can hadfield manganese steel castings be heat treated twice?
Of course, if this steel is heat treated correctly, may be treated as many times as needed.
Can spring steel be heat treated?
Definately spring steel can be heat treated and it has to be heat treated before it can be functioned as a spring. The common way to heat treat spring steel is by quenching and tempering.
Does diamond explode under immense heat?
No, diamonds are formed under immense heat and pressure.
What causes diamonds to form in the mantle?
Pressure and extreme heat.
Are chocolate diamonds formed under high pressure?
All diamonds are formed under high pressure - - and high heat.
Are pink diamonds naturally pink?
Yes, if they are natural diamonds. Diamonds can be treated or enhanced to 'bring out' a colour, so a faint pink diamond could be treated to enhance the colour and become a more intense pink. Enhanced diamonds are of a lesser value than naturally coloured diamonds. Today, most natural pink diamonds are produced from the Argyle mines in Australia, and are pink based on "...low levels of nitrogen impurities, their colour resulting instead from structural defects of the crystal lattice," according to Wikipedia.
How are American diamonds formed?
The same way diamonds all over the world are formed: intense high pressure and heat on carbon.
