Researchers have used a chemical model to form diamonds.

The diamond is one of the most precious gems around. It is a symbol of purity and eternal love, but this gem is not as rare as it has been believed to be. The formation of a diamond is a very common process and it has been replicated by researchers from John Hopkins University.

“Diamond formation in the deep Earth, the very deep Earth, may be a more common process than we thought.”Dimitri A. Sverjensky, geochemist at John Hopkins University and lead author of study said in a statement.

Using a chemical model, researchers have found that this precious stone can be formed much more easily in natural environment than previously thought. The common understanding is that diamonds are formed at high temperatures and pressures at depths of 140 to 190 kilometers in the Earth’s mantle. When different types of fluids moving through the rock interact with different oxidation states in environment, it results in the formation of a diamond.

Researchers believe that if the acidity level is increased during interaction between water and rock, diamonds can be created. While moving from one rock to another, water becomes more acidic because pH will fall naturally.

Though is will be a difficult task because the formation still depends on volcanic magma eruptions that arise from the depths of the Earth mantle. Moreover, researchers are not sure why the ‘redox reactions’ or change in oxidation state takes place.

The diamonds which will be formed by this 'new quantitative theory' will not be so massive to be placed inside rings. They will be only like few microns, hardly visible to naked eye.

“The more people look, the more they are finding diamonds in different rock types now,” Sverjensky said. “I think everybody would agree there’s more and more environments of diamond formation being discovered.”

Sverjensky’ chemical model is yet to be tested with actual materials. There is still a big concern whether it will be physically possible to create diamonds. It roughly requires 90 to 80 miles below the Earth’s surface at an intense temperature of about 1,650 to 2,000 degrees Fahrenheit. And the deepest the Earth is ever explored is not more than 8 to 9 miles.
