0.57 Carat E IF Round Diamond

To grow a Chemical Vapor Deposition (CVD) diamond, diamond plates are placed into a vacuum chamber, which is carefully injected with a hydrocarbon gas such as methane, and use high power microwave energy to break down the atomic bonds of the hydrocarbon gas. This separates the carbon atoms from the hydrogen atoms, and the resulting free carbon 'rains' down on the diamond plates, vertically growing the diamond atom by atom, like the way snow collects on the table.
