High hardness diamond

Synthetic atom density per unit volume than any existing pumping solids synthetic diamond, its hardness than natural diamond, called the world's most hard materials.

With natural diamond containing ninety-nine percent of the carbon-13 isotope. According to the scientists observed, with the carbon-13

Isotope intensity increases, the distance between atoms will be slightly reduced, prompting the hardness of diamond atomic arrangement slightly loose than natural

diamond. In the course of synthetic diamond , the first process by chemical vapor enriched isotope carbon-13 A

Alkyl gas carbon precipitation into polycrystalline diamond small pieces, and then use very high pressure to break down these small pieces, and then crystallized into weight up to 3

carat diamond block.
