"The synthesis of HD remains a challenge and even its existence remains controversial." The newly produced diamond has a hardness of 155 gigapascals (GPa), which is essentially a pressure measurement: ...

Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting graphite to extreme pressure and heat, researchers synthesized a rare ...

While many of these attributes were first identified in naturally occurring stones, recent advances in diamond synthesis have allowed researchers to begin to access diamond’s full potential.

Head of the Institute's Laboratory of experimental mineralogy and crystal synthesis Yuri Palyanov told ... It takes from ten hours to a few days to grow a diamond. It is impossible to find two ...
