Chemical Vapor Deposition Diamonds (CVD-D) are diamonds,
which are produced by the chemical vapor deposition. The advantage
compared to polycrystalline diamond (PCD), the high purity is
(99% diamond content) of the diamond layer and the resulting higher
hardness and wear resistance. The hardness of CVD-D is therefore almost identical.
with the hardness of MKD, but not anisotropic, this means not directional.
