Is it true the Diamond is not scarce?

Diamonds are always associated with expensive and luxurious. For men, buy diamond encrusted jewelry for their girlfriend or wife a sign of wealth. It was impressive that the diamond is a rare gem. But in fact, not entirely correct.

As quoted from Science Daily on Sunday, November 8, 2015, according to the findings of the Johns Hopkins University, diamond is not rarest as we imagine.

"Formation of diamonds in the ground, piece of land very deep, it could be more common than we think," said Dimitri A. Sverjensky, a geochemist from Johns Hopkins University.

The articles written by Sverjensky with doctoral candidate student Fang Huang published in the online journal Nature Communications. Report 'is a new quantitative theory in the formation of diamonds'. However, that does not mean you necessarily can easily find diamonds and bring it to market, and then go home with a lot of money.

The existence of diamonds in the ground is not a bit, however, whether or not taken depends on several things. One of them, whether or not the volcanic eruption of magma at a depth where diamonds. Others, diamond mentioned in the study is not only the type of diamonds used for jewelry, but when present it, is equipped with a microscope. In other words, not all types of diamonds are considered 'precious stones'.

By using models of chemicals, Sverjensky and Huang found that these precious stones can be formed in a natural chemical reaction that is simpler than the two main processes, which until now believed to be a diamond formation. Specifically, the model, which will be tested with real material, showed that diamonds are formed with rising levels of acidity in the interaction between water and rock.

The common understanding until now is that diamonds are formed in a fluid movement with reduced oxidation of methane or chemicals from carbon dioksisa. Oxidation produces a higher oxidation state, or increasing the electron. Keasaan oxidation reduction means lower, and the second reaction process called 'redox'.

"It is always difficult to explain why the redox," said Sverjensky, who is also a lecturer in the Department of Earth Science and Planet in Morton K. Blaustein. The reaction requires a different type of fluid that can be moved through the rock, to the environment that have different oxidation states.

Recent research shows that the water could produce diamonds because of the level of acidity (pH), which falls naturally, so it becomes more acidic while moving from one stone to another.

This discovery is one of the discoveries for 25 years, which gives insights into the nature of the diamond easily deformed. "More and more people are looking for, easier to find diamonds in different types of rock," said Sverjensky. "I think all would agree that more and more the environment in which the discovery of a diamond formation."

No more that reveal the number of diamonds greater availability, but according Sverjensky scientists today continue to work with chemical models. Not possible to physically explore the depths where diamonds are created - approximately 90 to 120 miles below ground level, with strong pressures and temperatures reached 1,650 to 2,000 degrees Fahrenheit (900 to 1,100 degrees Celsius).

Whereas, for the moment, the underground exploration of the deepest ever done is 8 to 9 miles below the surface. *** [EKA | FROM VARIOUS SOURCES | SCIENCE DAILY]
