Diamonds are one of many different forms that the element carbon can take, and it is much easier for carbon to form other substances, particularly coal or graphite, rather than diamond, which requires extreme pressure and blistering high heat to form.
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
It could take minutes or thousands of years, depending on the rate of cooling.
