U.S. Nevada University scientists have found a unique diamond with a super-solid ice shape, known as Ice-VII. The research was published in Science magazine.
As a rule, super-solid ice shape is of extraterrestrial origin. Its molecules, unlike those in a simple ice (Ice-I), have a cubic molecular shape. Such arrangement on the Earth can be made only in laboratories.
The diamond was found amid the patterns taken from the Earth’s mantle. Experts analyzed the stone, they figured out that it was Ice-VII. This phenomenon was recorded in entirely natural Earth surroundings for the first time.
