Researchers at Ehime University and Sumitomo Electric Industries of Japan have announced that they have successfully developed the world's largest and hardest artificial diamond with a diameter of 4 mm, which is expected to be used in the field of hard metal processing. Previously the largest artificial diamond was only 1.5 mm in diameter.
This is a polycrystalline diamond made from a diamond of 10 to 30 nanometers in diameter. It is a faint syrupy color and is not as dazzling as a jewel. However, unlike single crystal diamonds which are easily broken in the direction of force, this artificial diamond can withstand forces from all directions up to twice the hardness of natural diamonds.
