Is a cvd diamond a real diamond?

Yes.Both cvd diamonds and hpht diamonds are real diamonds. Although they are both grown in the laboratory, they are gem-quality diamonds. Their element structure and physical, chemical and optical properties are the same as natural diamonds, so they are all real diamonds.

What is the CVD diamond

CVD stands for chemical vapor deposition and is another method of making diamonds in the laboratory. Specifically, diamonds grow from hydrocarbon gas mixtures and are subjected to moderate pressure and temperature in a vacuum chamber.

The history of CVD cultivated diamonds can be traced back to 1952. William Eversole of the US Federal Silicon Carbide Company successfully grown synthetic diamonds with carbon-containing gas under low pressure conditions.

It was not until the 21st century that the research and development of gem-grade CVD single-crystal created diamonds made a breakthrough: the American Apollo Diamond Company successfully cultivated the first batch of colorless gem-grade CVD diamonds in 2007
