Where Diamonds Come From

Updated on April 4, 2013

Diamonds are well known for not just their use in jewelry but also for their applicable uses. Many cutting tools are tips with diamond to cut and grind other materials. But diamonds can also be noted for their sound. Diamonds are used in speakers as well. Diamond, due to it's rigidity, vibrates in a way that is thought to keep great sound quality longer. The diamonds used can made in the lab, but the natural processes take much more time and the diamond goes through a much more wild adventure.

The diamond is formed by intense pressure and heat , about 2,000 degrees Fahrenheit. The pressure in which a diamond is formed is found at 100 to 200 kilometers in the Earth's mantle and can take millions to billions of year to turn into its pure state. Also, the structure of diamond is different from it's constituent, graphite. Diamond atoms are arranged in a crystalline lattice. Graphite, on the other hand is made up of hexagonal layers that are stacked upon each other. This structure gives the two materials an entirely different appearance.

Graphite, diamonds, and coal are all made up of carbon atoms, but opposite of popular belief, diamond are not thought to come from coal. Among the evidence that diamonds are formed independently from coal is the fact that diamonds out date plant life, which is part of the process to create coal. Diamonds are dated back to 3.3 billion years-old.

Access to diamond comes in different forms. Magma in the Earth's mantle pushes diamonds up into the surface. Diamonds are then found in deposits called kimberlites. Diamonds are also found in impact sites of meteors. The astronomical speed and heat is sufficient to create the processes necessary to convert carbon materials into diamonds. Also, diamonds can be found in asteroids in space.

The natural sequence of the formation of diamonds is one of extreme pressure, heat, and time. These crystalline structure are the hardest material on our planet and thus used form many industrial uses such as cutting. Coal is now doubted to have played a role in the formation of diamonds. The evidence is in the old-age of the diamonds themselves. Not only are diamonds formed naturally in the Earth's mantle, they are also connected to the immense force of meteors. Diamonds are relished by jewelers but are also a fascination to geologists.

      Very interesting,learned a lot that I didn't know about diamons.
