Japanese scientists have created what is believed to be the world's hardest diamond.
A team of researchers at Ehime University in Matsuyama, Japan created the world's first perfectly spherical diamond and named it the Hime diamond. It is a perfect four-carat sphere with a diameter of 7.5 mm.

The potential for this technology’s usefulness in order to shape an artificial diamond into a perfect sphere is vast.

In 2003 the research center synthesized the first Hime diamond -- a tiny grain of diamond measuring less than 1 mm wide. The center combined carbon atoms by subjecting them to 150,000 times the standard atmospheric pressure and temperatures of 2,300°C.

By 2010, the research team was able to create Hime diamonds up to 1 cm wide, with plans to commercialize the diamond. “As a product for industrial use, its lifetime is several times longer than that of an ordinary diamond," the university's Tetsuo Irifune said.

Hime diamonds are far harder than naturally formed diamonds. They have a uniform degree of hardness throughout their structure, whereas there are changes within parts of a natural diamond.

Did you know that there is something harder than a Hime diamonds?
Heb 3:13  But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.

Diamonds are not as hard as a sin-sick heart, and unlike a hard diamond, we can choose to soften our hearts toward God.
Heb 3:8  Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:

How terrible for any human being to rebel against the Creator!
