Small Inclusions of Unique Ice in Diamonds Indicate Water Deep in Earth’s Mantle
Mar 12, 2018 by News Staff / Source



The team, led by University of Nevada, Las Vegas geoscientist Oliver Tschauner, found inclusions of the high-pressure form of water called Ice-VII in natural diamonds sourced from between 255 and 410 miles (410-660 km) depth.

“In the jewelry business, diamonds with impurities hold less value,” the researchers said.

“But for us, those impurities — known as inclusions — have infinite value, as they may hold the key to understanding the inner workings of our planet.”
