    The common element between the two is that they both are made up of carbon. The element carbon exists in the earth in different forms like coal, graphite, diamonds, etc. So the common factor between coal and diamonds is that they contain carbon. Then why they look different. Is it possible that diamonds are formed from coal? Let us find out.
