Scientists have a new theory on how diamonds are formed.
Scientists recreated the same environment with extreme temperature and pressure that is found around 200 km under the sea where diamonds are formed. They showed that seawater from sediment from the bottom of the ocean reacts in the right way to produce the balance of salts found in diamond. Earlier scientists were not able to find where the salts found in diamonds came from. A scientist involved in the research said, "We knew that some sort of salty fluid must be around while the diamonds are growing, and now we have confirmed that marine sediment fits the bill."
