No, a lump of coal cannot turn into a diamond, as the two are made up of entirely different substances, both in form and chemical composition. A diamond is an allotrope of carbon, wherein the atoms are arranged in a particular lattice structure.
This arrangement of atoms gives diamonds their signature crystal structure, which makes them incredibly hard, with an incredibly high melting point. Coal, on the other hand, is a sedimentary rock composed of carbon and other elements, such as sulfur and nitrogen.
In its natural form, coal has a much looser structure and the carbon atoms are arranged differently.
The process of transforming coal into diamond is known as artificial diamond synthesis, and it involves subjecting the coal to temperatures over 3000°C and pressures of up to 60,000 atmospheres. This process rearranges the atoms in the coal and it is possible to create artificial diamonds from coal.
However, the resulting diamonds are lower quality and are not as durable or valuable as natural diamonds.

Can coal become diamond?
No, coal cannot become diamond. Diamonds are formed deep within the Earth’s mantle, at high temperatures and pressures. Carbon atoms within diamonds are arranged in a strong, symmetrical lattice, which is responsible for the diamond’s incredible strength, hardness, and brilliant sparkle.
Coal, on the other hand, is a sedimentary rock that is composed of mostly carbon, but has a more disorganized, random arrangement. Coal is formed through the compaction and heat of organic matter over thousands of years.
Because of the difference in formation, as well as the difference in composition, it is impossible for coal to turn into diamond.
How long does it take for coal to turn to diamond?
It usually takes millions of years for coal to transform into a diamond. This complex process requires the force of Earth’s internal heat and pressure to slowly transform the carbon atoms of the coal into the iconic crystal structure of a diamond.
This process occurs naturally over time and most often happens under extreme pressure around 100 miles below the earth’s surface. By simulating these specific conditions and timescales in a lab, however, it is possible to speed up the process of transforming coal into a diamond.
In lab conditions, it is estimated that replicating the natural process and turning coal into a diamond particle takes anywhere from a few days to weeks, depending on the size and quality of the diamond.
However, the properties of lab-made diamonds are not equal to those of a naturally formed diamond, as the conditions in lab settings are not able to replicate the power, pressure and time that occurs in the natural environment.
What type of rock is diamond found in?
Diamonds are most often found in kimberlite rocks, also known as kimberlite pipes. Kimberlite is an igneous rock that is formed deep within Earth’s mantle and is ejected towards the surface during a volcanic eruption.
It is made up of basalt, pyroxene, and garnet and contains a lot of carbon dioxide, hydrogen, and sulfur. Kimberlite is usually found in mountainous and hilly areas around the world, and it is sometimes referred to as “blue earth”.
As diamonds are merely crystallized carbon, they are found within the kimberlite rocks that form during volcanic eruptions. Due to its hard and dense composition, diamonds from kimberlite rock often remain intact after being brought to the surface.
Why are diamonds clear but coal black?
Diamonds are clear because of the way the carbon atoms that make up the diamond are arranged – the arrangement that makes diamond so strong and hard is also responsible for allowing it to transmit light without causing reflection or scattering, leading to its clear and transparent appearance.
In contrast, coal is made up of carbon atoms arranged in a much different way. Coal is composed of much larger particles of carbon that have multiple layers containing crystalline structures that are randomly arranged.
This structure causes light passing through the coal to scatter and be absorbed by the carbon atoms, resulting in the material appearing black.
What transforms coal into diamond?
The process of transforming coal into diamond is known as diamond synthesis. This process occurs when carbon atoms are exposed to extremely high temperatures and high pressures, which simulate the same conditions found deep within the Earth.
Heat and pressure cause the atoms to rearrange themselves and bind together in a crystalline formation — a diamond. This process was first accomplished in 1954 using a large press and electrical current to apply the necessary pressure and heat.
Today, scientists can create a diamond more efficiently and in a wider variety of colors, shapes and sizes. In order to create a larger diamond, it can take up to several days to generate the right temperature and pressure.
How quickly can you make a diamond?
Creating a real diamond requires immense heat and pressure, which cannot be created in a lab setting. The process of making a real diamond can take up to 3-6 months, depending on the size and quality of the diamond.
Natural diamonds are formed in the Earth’s mantle at a depth of 100-200 kilometers, involving temperatures of 950 to 1700 degrees Celsius and pressures of 45 to 60 kilobars. Although modern diamond synthesis techniques have been in development since the 1950s, they have only recently been perfected to create gems of similar size and quality as those found in nature.
Currently, the most popular method for synthesizing diamonds is called high-pressure, high-temperature (HPHT) technology. In this method, a diamond seed is placed in a growth chamber with carbon-rich gas and heated to about 1300°C and exposed to pressures up to 50,000 atmospheres.
The diamond seed is then exposed to a microwave field, causing the carbon atoms of the gas to attach to the seed and create a thin layer of diamond more than a few nanometers thick. As the process is repeated, additional layers of diamond are added until a full size diamond is created.
Scientists also continue to research and develop other techniques, like chemical vapor deposition and physical vapor deposition, which could potentially speed up the process of creating diamonds in the future.
Can we make diamond at home?
No, it is impossible to make a diamond at home. Diamonds are formed deep within the Earth’s mantle under extreme pressures and temperatures. These conditions are impossible to replicate in a home setting, so in order to make a diamond, you must obtain a rough diamond from mined deposits or a lab-created diamond.
To cut and polish a diamond from a rough diamond, specialized tools and techniques must be used, which are complex and costly. Although attempting to make a diamond at home is impossible, it is possible to cut and polish the finished diamond at home.
You can purchase diamond cutting tools online, or have a professional jeweler cut and polish the diamond for you.
What creates a diamond?
Diamonds are created when carbon, a plentiful element found on Earth, is subjected to intense heat and pressure. These conditions can be found deep beneath the surface of Earth’s crust, and it is believed that diamonds are formed between 150 and 400 kilometers below the surface.
Small pockets of intense heat and pressure form the ideal spots for diamonds to form. In order for the diamond to form and remain intact, the carbon must be subjected to temperatures of 900-1300 degrees Celsius, and must be set to pressure between 45 and 60 kilobars.
This heat, pressure, and carbon combine to create the diamond as we know it, a smooth and beautiful gemstone, and is believed to have formed in the Earth’s mantle, pushing to the surface via volcanic eruptions.
What stone is as strong as a diamond?
Moissanite is currently considered the gemstone that is as strong as a diamond. Moissanite is a crystalline form of silicon carbide and is exceedingly rare on earth. It typically only occurs in the form of tiny crystals, but large, gemstone-quality stones can be manufactured in a lab.
It is nearly as hard as diamond, though the structure of the two stones is quite different. Moissanite is considered to have a hardness of 9. 25 on the Mohs scale, while diamonds are rated at 10. The brilliance, fire and luster of moissanite is also very comparable to diamond.
In fact, it is often judged to be superior to most other gemstones in these aspects. However, it is not just as expensive as a diamond, which makes it an attractive alternative to those looking for diamond-like qualities without the price tag.
Is a diamond a lump of coal?
No, a diamond is not a lump of coal. A diamond is a naturally occurring material composed of pure carbon atoms in an atomic structure that is extremely strong and stable. Coal, on the other hand, is a combustible, organic rock formed millions of years ago when organic material such as dead plants and animals were compressed and heated by natural forces deep within the earth’s crust.
Coal is composed primarily of carbon, but also contains traces of other elements including hydrogen, oxygen, sulfur, and nitrogen. The two materials can look similar in their raw forms, but a diamond’s atomic structure makes it much harder and more durable than coal.
Additionally, diamonds are valued because of their beauty, extreme durability, and rarity, while coal is has been used as an energy source and has no intrinsic value.
Are diamonds found around coal?
No, diamonds are not found around coal. Diamonds are generally found deep in the earth’s mantle in a layer of rock known as kimberlite or lamproite. Kimberlite and lamproite pipes are formed by volcanic activity and can sometimes be uncovered by the erosion of the Earth’s surface.
They contain a mixture of substances, including diamonds, but not usually coal. In addition, diamonds are created over a very long period of time, so they are not found in abundance near the surface as they are too deep as compared to coal.
Coal, on the other hand, is made over a relatively short period of time and is much more abundant at the surface than diamonds.
Are diamonds coal or carbon?
No, diamonds are not coal or carbon. Diamonds are a crystalline form of pure carbon, produced under intense heat and pressure deep in the Earth’s mantle. Carbon is thought to be the primary element found in the Earth’s mantle, and in the diamonds that form in Earth’s mantle due to the intense heat and pressure.
Coal, on the other hand, is a combustible black or brownish-black sedimentary rock which is formed by the decomposition of plant matter. The process of creating coal takes hundreds of millions of years and does not involve the intense heat and pressure that is necessary to create a diamond.
Why coal is called diamond?
Coal is sometimes referred to as a “diamond” because of its hardness, blackish color, and similarity to diamond in terms of the energy it can generate when burned. Coal is a non-renewable resource and the most abundant fossil fuel in the world, making it a valuable commodity for generating electricity, providing heat, and creating other products.
Coal has been used for centuries and is considered to be the most efficient and economically viable fuel source for many countries. Although diamonds can be found in nature, coal is formed from carbon in the ground that is pressure compressed over millions of years.
The high-pressure environment and intense heat creates a mass of carbon atoms, with each having a strong bond that is difficult to break, making coal much like a diamond in terms of its toughness. In addition, when coal is burned the high temperature causes the carbon molecules to form an even more rigid, diamond-like structure that produces a lot of energy.
How is diamond different from coal?
Diamond and coal are both composed of carbon atoms but the arrangement of those atoms is what makes them distinctly different. Diamond is an allotrope of carbon where the carbon atoms are arranged in a crystal lattice structure.
This structure is exactly the same in a diamond no matter its size or shape and it is what makes it the hardest known naturally occurring substance. This structure also gives diamonds their beautiful sparkle.
Coal, on the other hand, is an organic sedimentary rock composed of carbon atoms. In coal, these atoms are arranged in an irregular amorphous structure which allows them to easily be broken down during combustion.
This structure makes it very useful as a fuel source and industrial feedstock but also much softer and less valuable than diamond.
