Answer 
Carbon changes into diamond beneath the earth under high pressure and temperature. This process might have taken millions of years. Under extreme pressure and heat, the carbon atoms adopt a different bonding structure ( bonding structure you will study in higher classes if you opt science )

In simple terms, when graphite is exposed to high temp. and pressure it rearranges to form diamond. Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and...

Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).

Carbon chabges into diamond in the depths of the earth under high pressure and temperature...this process takes millions of years . carbon u der this process takes a different structure and squeeze into huge three dimensional network of interlocking tetrahedra

when carbon is subjected to Very high pressure and temperature, its molecular structure changes to tetrahedral shape,resulting in diamond so that it could withstand the pressure, to oppose it, in accordance with law of nature which states that : "NATURE OPPOSES CHANGE". e.g. Le Chatelier's principle. Now,...

Now, so much heat provides enough activation energy required to change the molecular structure of carbon, hence turning it into Diamond. But when diamond is taken out it retains it's molecular shape as it do not have access to the amount of heat needed to change it's molecular shape/structure read less

Under extreme pressure and heat, the carbon atoms adopt a different bonding structure. Instead of the conventional graphite rings, the carbon atoms squeeze together in a huge 3-dimensional network of interlocking tetrahedra.

Under extreme heat and pressure the carbon atoms squeeze together in a huge 3-dimensional network of interlocking tetrahedra which we called Diamond

The natural or original diamonds are formed by the extreme heating and extreme pressure acting on carbon atoms underneath the earth crust. So those extreme pressure and temperature forces the carbon atoms to organize in a tetrahedral form i.e. diamond rather than forming graphite. This process of changing...
read more The natural or original diamonds are formed by the extreme heating and extreme pressure acting on carbon atoms underneath the earth crust. So those extreme pressure and temperature forces the carbon atoms to organize in a tetrahedral form i.e. diamond rather than forming graphite. This process of changing in the phase on application of extreme temperature and extreme pressure is termed as phase transformation.So the carbon transforms its phase to tetrahedra form when extreme heat of about 2200 degrees Fahrenheit and extreme pressure is applied. Synthetic diamonds are formed nowadays by either High temperature and high pressure technique which is same as the process occurring in earth crust. But it will be having some impurities. Another method is by using chemical vapour deposition technique. read less

Natural diamonds, the hardest substance known to man require very high temperatures (ranging from 900 to 1300 on the Celsius scale) and pressure that exists only at depths of 87 to 120 miles (140 to 190 kilometers) in the Earth’s mantle to form. Unlike other gems which are formed by a combination of...

Unlike other gems which are formed by a combination of elements, diamonds are made up of one single element- Carbon. Carbon-containing minerals present in the Earth at those depths, crystallize to form diamonds because of the immense pressure together with the heat from molten magma. read less
