I think the only difference is the exposure to pressure and time ... (which is thousand years)
Also, diamond is much more dense and burns more cleanly into CO2 because it is pure carbon, unlike coal, which also has hydrogen in it.

The first sentence above is wrong on time. Most of the world's coal reserves formed more than 300 million years ago, over some millions of years, in the Carboniferous Period. Not "thousand".
There is another, very big difference. Coal is a sedimentary rock, and hydrogen would not make it burn less cleanly - even if it could exist within coal as hydrogen alone. Most of the impurities in coal are sulphur and organic compounds.
Diamond occurs within certain igneous rocks formed at great depth hence great pressure and temperature.

How many years does it take for coal to change into a diamond?
It would be highly unusual if coal ever turned into diamond. Diamonds are formed only at depths in the crust of more than 60 miles. Coal on Earth does not exist at anywhere near this depth.
How to tell if a diamond is real?
Supposedly the only way to distinguish the best manufactured white diamond from a real diamond is the fake diamonds are flawless, and no real diamond can be truly flawless. I always wondered about this though, because how hard would it be to add flaws to a fake diamond to make it appear real? So my opinon is there is no way to tell the difference between a real diamond and a fake diamond.
Why is diamond more dense than coal?
Because a diamond has more carbon bonds than coal. Carbon bonds are very strong and can only be broken in one direction. Diamonds have 3 carbon bonds, which makes it very hard. Diamonds can only be cut in one direction, that is because of the number of carbon bonds.
What is the difference between coal and flint?
Coal is Black and shiny, and will sheer easily. It is a mixture of many different organic compounds. Found/mined in specific minefields in the UK. Flint is white/colourless and does not sheer easily(very hard). It is only one compound. sand (silicon dioxide) or possibly other crystalline solids held in the flint chemical lattice. It is found mainly in the clay vales of Southern England.
Which one is an element between coal steel tin and water?
Only tin is a chemical element. Coal is not an element because it is impure.
Is their a difference between the us and European versions of Pokemon diamond pearl if their is what are they?
There is only one difference.That difference is that they have it in European.

What is the difference between Pokemon mystery dungeons explorers of time and explores of darkness?
The only difference is that there are different Pokemon in each version like Ruby/Saphire or Pearl and Diamond
What is the difference in ARB and ADB Coal?
ARB : As Received Basis ADB : Air Dried Basis Note: There is no difference between ARB and ADB both are same only if your are seen the Quality means.
What is the difference between a square and a diamond?
A square must have all four angles equal (at 90o) whereas in a diamond only the opposite angles are equal. A square is a diamond with all four angles right angles.
Why is matter composed of 2 or more elements?
Matter also may composed of one element only as Coal, Graphite and Diamond are only Carbon.
What is the structural difference between diamond and coal?
The difference between graphite and diamond is in the three-dimensionalarrangement of the carbon atoms in the material. Graphite is made of flatsheets of carbon atoms in a hexagonal arrangement. The sheets stack oneover the other, with only weak interactions between sheets. Diamond is notarranged in sheets; instead, each carbon atom is connected to four others ina tetrahedral arrangement. It turns out that this arrangement is not asdifferent from the structure of graphite as it sounds. If the sheets ofgraphite are compressed close enough together, the carbon atoms will be injust about the right position to make the bonds of diamond. In fact, athigh temperatures and pressures, this indeed happens.Richard E.
