What is the link between coal and diamond?

Answer 1

Coal has never been at sufficient depth and temperature to be turned into diamond. Coal is simply fossilized plant remains that are high in the element carbon, of which the mineral diamond is also composed.

Answer 2

No, you cannot make diamonds by burning coal. To turn coal into diamonds, you need tremendous heat and also tremendous pressure. Merely burning the coal is not nearly enough heat, and you would also still need to increase the pressure.

Another Answer

The molecules in coal are arranged differently from the molecule arrangement in diamond -- although both are allotropes of carbon, you cannot form a diamond from coal under any pressure or temperature.

Answer 3

Both coal and diamond are made of carbon atoms, but their formation processes are very different. Coal is formed from decaying plant matter under high pressure and heat over millions of years, while diamonds are formed deep within the Earth's mantle under extremely high pressure and heat. This difference in formation conditions leads to the distinct properties and value differences between coal and diamonds.

Answer 4

Both coal and diamond are allotropes of carbon, simply with different atomic patterns.
