Many people believe that diamonds are formed from the metamorphism of coal. That idea continues to be the "how diamonds form" story in many science classrooms. Coal has rarely - if ever - played a role in the formation of diamonds.
Coal and diamonds are derived from carbon, but this doesn’t mean a similar carbon composition is used to form these two; far from it. Diamonds are made from pure carbon deposits. That’s one of the reasons behind the clarity of these precious stones. Meanwhile, the carbon used to form coal is packed with impurities we talked about before.
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is a tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water.
While it's a common misconception, the formation of diamonds and coal involves different processes and conditions. Here's a detailed breakdown of why it's not true: Coal: Coal is a sedimentary rock formed from the compressed remains of ancient plants buried near the Earth's surface.
13 Μαΐ 2020 · Diamonds and coal are both, at their base, different forms of the element carbon (C on the periodic table). And yes, pressure is a key part of what turns decaying carbon-based life forms such...
17 Μαΐ 2023 · How are diamonds formed, simple theories for kids (earth’s mantle, asteroid), what element are they made of (can coal turn into diamond), how long does it take
26 Μαΐ 2023 · Are Diamonds Made from Coal? So diamonds were once pieces of coal that have been transformed under high pressure and temperature, right? Nope! This is an old wives' tale, just like "another drink will cure your hangover" or the idea that being out in the cold causes you to catch a cold.
