Could you crush a piece of coal under enormous pressure to make a diamond?
YES, but it would take a boxcar size piece of coal to make a tiny diamond.
Is coal a black diamond?
No. coal is coal and diamond is diamond. They are both formed from carbon, but diamond is much harder than coal.
How long does it take a piece of coal to become a diamond?
It takes extreme pressure and tens of thousands of years, but, yes, if the conditions are right, a diamond can result. Coal and diamonds (and graphite too!) are all made from purely carbon atoms! They are just different forms of the same element! Pretty amazing, eh?!
What phases does coal go through before it forms a diamond?
A diamond is not formed from coal. Diamond and coal are both allotropes of carbon, and are formed by different processes.
Why does a diamond turn into coal when it's burned?

What is another name for rhombus?
It is sometimes called a diamond - as in the suit in playing cards, not a jumped-up piece of coal!
Is diamond and coal minerals?

What type of coal turns into a diamond?
No 'coal' turns into 'diamond'. Both coal and diamond are composed of carbon, each being formed at different layers in the earth's mantle.
