The process of turning coal into diamonds is called carbonadoing, and it requires a lot of heat and pressure. The first step is to heat the coal to around 2,000 degrees Fahrenheit, which produces a black, sooty substance called char. The char is then placed under immense pressure, which causes it to turn into a diamond. ...
