The state-run university’s Geodynamics Research Center said it has processed an artificially produced diamond, named Hime, into a perfect four-carat sphere with a diameter of 7.5 millimeters.
In 2003, the research center synthesized a tiny grain of Hime diamond measuring less than 1 millimeter wide. The centre combined carbon atoms by subjecting them to 150,000 times the standard atmospheric pressure and temperatures of 2,300 C.

By last year, the research team had become able to create Hime diamonds up to 1 centimeter wide, they said.
Hime diamonds are far harder than naturally formed diamonds. They have a uniform degree of hardness throughout their structure, whereas this changes in different parts of a natural diamond, according to the centre.
