CVD diamond (also known as Synthetic diamond, Chemical vapor deposition diamond, laboratory-grown diamond, laboratory -created diamond )is diamond produced in an artificial process, as opposed to natural diamonds, which are created by geological processes.
CVD single crystal diamond properties:
Since CVD diamond does not contain any metal catalysts, its thermal stability is close to that of natural diamond. Like high temperature and high pressure artificially synthesized polycrystalline diamond, CVD diamond grains are also arranged in disorder, without brittle cleavage planes, so they are isotropic.
