my answer is how many days does coal turn into diamond 3nfgerhg8788
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
The mineral that takes millions of years to form is a diamond. These grow in caves and form on walls and ceiling's. The diamond is said to be the hardest substance in the world until carbon fiber nano tubes came along.
It could take minutes or thousands of years, depending on the rate of cooling.
The average growth rate is 0.13 mm a year
