  • Why are diamonds made from coal?

  • Turns out, the answer has a lot to do with why life, itself, is based on carbon. Coal is the compressed remains of ancient plants, dinosaur swamps sitting in the palm of your hand. But there are diamonds that are older than terrestrial plants. That fact alone should tell you that diamonds are not actually made from compressed coal.

  • What is the difference between coal&diamonds?

  • 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.

  • What is the difference between diamonds and Co-coal?

  • Coal is also formed from carbon, but is formed much closer to the earth鈥檚 surface, about two miles down. When coal is mined, miners go right to the source where the coal is formed. Diamonds, on the other hand, are brought close enough to the surface to be mined by volcanic eruptions.

  • Is CO2 coal a probable carbon source for diamond formation?

  • Coal is not a probable carbon source for this diamond-forming process. The most likely carbon sources from the subduction of an oceanic plate are carbonate rocks such as limestone, marble, and dolomite, and possibly particles of plant debris in offshore sediments. Asteroid Impact Diamonds:…
