Diamonds created using the CVD Method are chemically, physically and optically the same that natural diamonds that are created deep within the earth. First, a small layer of naturally occurring diamond that is made entirely of carbon is sliced to create the diamond seed. The CVD plasma reactor can accommodate the sliced diamond seed which is ready to grow. The reactor is a machine which provides the suitable condition for the formation of lab grown diamonds. The controlled conditions in the CVD process along with the precursor gases bit entering into the diamond seed, then the carbon particles disintegrate to form layers on the diamond seed to create the diamond.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The setup:<\/span><\/strong> A diamond growth chamber is created, consisting of a reactor chamber with a microwave power source, gas inlet system, and substrate holder. The chamber is designed to create a controlled environment for diamond growth.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Diamond growth:<\/span> The high-energy species in the plasma break down the carbon-containing gas molecules, releasing carbon atoms. These carbon atoms settle on a substrate, typically a flat diamond seed or a wafer, and start to form diamond crystals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
