Diamonds are a girl’s best friend, but where do they come from?

Small amounts of salt trapped in diamonds show the precious stones are made from old soils that were buried deep in earth’s crust, according to new research from a team of scientists in Australia.

The researchers were able to conduct experiments which show that the seawater in the sediment of the ocean floor, responding in the right way for making the balance of the salts found in diamonds.

She had again the extreme pressures and temperatures, which is more than 124 miles under the ground.

“There is a theory that the salts trapped in diamonds came from marine seawater, but could not be tested,” lead author Michael Judgment, who works at the Goethe University and the Johannes Gutenberg-Universität in Germany, said in a statement. “Our research showed that they are from marine sediments.”

For the process to work, a large part of the seabed would have to slip down to a depth of more than 124 kilometers under the surface very rapidly in a process known as subduction, scientists said.

According to the researchers, the rapid descent is necessary because the sediment must be compressed to more than 40,000 times the atmospheric pressure, before it can be melt at temperatures of over 800 degrees Celsius, or 1,472 degrees Fahrenheit.

The study, published in Science Advances, settles a longstanding debate about the formation of diamonds.
