Characteristics Of Gia Certified Lab Grown Diamonds
There are two large-scale diamond deposition methods on the market: chemical vapor deposition, CVD and high pressure high temperature, high temperature high pressure, HPHT.
(1) High temperature and high pressure (HPHT) diamond cultivation technology: the first generation diamond growth technology, which completely simulates the growth process of natural diamond, reproduces the reaction of ground carbon layer, and converts graphite into diamond grown in the laboratory;
(2) Chemical vapor deposition (CVD) diamond culture technology: The diamond is grown in a high temperature and low pressure environment using microwave, using sand particles or small pieces to the size of diamond as seeds. The carbon atoms are added in the plasma reactor to 5537 ℃, so that the atoms can attach to the thin diamond crystals one by one. The "growth" gradually becomes a large diamond cultivated in the laboratory.
