  • Metamorphic

    Graphite and diamond are two minerals that are both made entirely out of carbon. If we put graphite under a huge amount of pressure, the carbon atoms will be squeezed together and will rearrange themselves into the more compact crystal structure of diamonds. This change happens without any melting of the rock.
