Natural diamonds are formed deep within the earth's mantle. According to Wikipedia:
"These depths are estimated between 140 and 190 km though occasionally diamonds have crystallized at depths about 300 km as well. The rate at which temperature changes with increasing depth into the Earth varies greatly in different parts of the Earth."

Are diamonds made deep underground in a rock?
A diamond is a metamorphic rock formed from carbon. Diamond formation requires intense heat and extreme pressure, which naturally occurs deep underground.
What is the first stage of a diamond?
The first stage of a diamond is its formation deep within the Earth's mantle, where carbon atoms are subjected to high pressure and temperature over millions of years. This process transforms the carbon into diamond crystals through a combination of heat and pressure.
How are artificial diamonds made using thallium carbonate?
Thallium carbonate can be used as a catalyst in the high-pressure, high-temperature process of creating artificial diamonds. This process involves subjecting carbon to extreme heat and pressure in the presence of a catalyst, like thallium carbonate, to facilitate the transformation of carbon into diamond crystals. Thallium carbonate helps reduce the activation energy required for diamond formation, allowing for the creation of artificial diamonds in a shorter amount of time compared to natural diamond formation.
What two forces cause the formation of metamorphic rock?
Heat and pressure.
What rock is fromed by heat and pressure?
A diamond is formed.
How do coal and diamond differ?
Coal and diamond are both made of carbon, but they have different structures that give them distinct properties. Coal is formed from decaying plant matter under pressure, while diamond is formed under extreme heat and pressure in the Earth's mantle. This difference in formation makes coal soft and brittle, while diamond is the hardest known natural material.
What material in nature can turn into a diamond?
Only carbon can turn into a diamond. In addition to the occurrence of the mineral, in order to form a diamond, enormous pressure and intense heat are also required. This combination of natural elements occurs deep within the earth's mantle.
Is a dimond a nonrenewable resource?
Diamond is formed when carbon is placed under high pressure and heat. The pressure and heat necessary for its formation is not found on the surface of the earth, but rather deep inside it. This fact, plus the sheer amount of time necessary for it to form, makes it a nonrenewable resource.
How does heat and pressure affect the type of coal formed?
Heat and pressure during the process of coal formation determine the type of coal formed. The higher the heat and pressure, the more carbonaceous the coal becomes, resulting in higher carbon content and quality. Low heat and pressure conditions lead to the formation of low-grade coals like lignite, while high heat and pressure conditions promote the formation of high-grade coals like anthracite.
Which of the physical processes is the formation of metamorphic rocks?
Heat and Pressure
Does diamond explode under immense heat?
No, diamonds are formed under immense heat and pressure.
What does graphite turn into when put under pressure?
Graphite turns into diamonds when put under extreme pressure and heat. Diamond is a denser and harder form of carbon compared to graphite.
