    The first of the man-made Diamonds, also known as Synthetic Diamond or CVD Diamond, was made in 1956 by General Electric with the High Pressure, High Temperature (HPHT) process. The HPHT process growth imitates a Natural Diamond formation, but with carefully selected input materials to catalyze crystal growth.

    CVD Diamond - FAQ

    For diamond CVD a carbon containing gas is decomposed and the carbon atoms are deposited on a surface. By proper conditions the growth of diamond crystals can be enhanced and the growth of graphite is suppressed. How does it work ? For diamond CVD atomic hydrogen plays a key role. It is obtained by dissociating hydrogen molecules (H2).

The electron shell configuration of carbon is 1s 2 2s 2 2p 2.Carbon has a valence of four since four electrons can be accepted to fill the 2p orbital. Diamond is made up of repeating units of carbon atoms
