  • How are diamonds formed from coated coal?

  • Coal is subjected to various geological processes that change its chemical composition to form graphite. This process requires suitable conditions and millions of years to take place. Diamonds are formed deep inside the earth, where the temperature and pressure are very high. They are transported to the surface of the earth by the molten magma.

  • Where do Diamonds get their carbon?

  • Coal could be present in the target area of these impacts and could serve as the carbon source of the diamonds. Limestones, marbles, dolomites, and other carbon-bearing rocks are more likely carbon sources than coal.

  • Why are diamonds harder than coal?

  • Since coal is formed near the surface, the heat and pressure are far less severe. Diamonds require temperatures of about 2200 degrees Fahrenheit, and pressure of about 725,000 pounds per square inch. It is this extreme heat and pressure, followed by cooling, which gives diamonds hardness not found in coal or any other substance.

  • Where do diamonds come from?

  • Carbon dioxide located about 100 miles beneath the surface of the earth is the source of diamonds. Coal is also formed from carbon, but is formed much closer to the earth鈥檚 surface, about two miles down.
