Identify Man Made CVD Synthetic Diamonds Education

To identify man-made CVD synthetic diamonds was never easy. Lab-grown diamonds either produced by HPHT or chemical vapour deposition technology. CVD diamonds uses includes cutting tools, thermal conductors & consumer diamond gemstones. Even to tell if a diamond is real or fake is sometimes hard for the experienced jeweller.Identify man made CVD synthetic diamonds

However, there is very few information available on the web. Below are some sure ways.

7 Tips to Identify man made CVD synthetic diamonds

  1. Use Microscope:  Keeping stone under the microscope, you can observe some characteristic strain patterns which differ from natural diamonds.
  2. Use DiamondView Machine: DTC’s recently launched DiamondView machine. It is designed to detect synthetic diamond. CVD synthetic diamonds turns to strong red fluorescence under high-energy UV radiation in the DiamondView machine.CVD DIAMOND in Diamondview
  3. Understand Inclusion Pattern: Some trustworthy laboratories says inclusions can show up in natural diamonds as well but tend to be more dispersed compared to synthetic diamonds.
  4. Spectroscopy Instrument: CVD diamonds can also detect using spectroscopy instrument. CVD diamonds are relatively strong photoluminescence emission at 737 nm due to trace impurities of silicon. Here the game becomes easy because silicon is not found in natural diamonds.
  5. Diamond Tester: Using a dual electronic diamond tester which that tests both thermal & electrical conductivity. hence helps you to make sure the stone you’re examining is a diamond.
  6. Check fluorescence: Examine the stone with an ultraviolet lamp that provides long-wave and short-wave emission. If the stone is fluoresced blue, it’s not synthetic. But natural diamonds fluoresces many colours some of the most common are blue, yellow and white.

Note : To identify man-made CVD synthetic diamonds you can even visit a local jeweller shop. However even expert finds hard to identify man-made CVD synthetic diamonds, thus we recommend to submit your stone to GIA or other Labs for verification.

We know it’s hard to identify cultivated diamonds from natural for consumers. The reason for sharing this article about “how to identify man-made CVD synthetic diamonds” is just to give the basic idea about lab-grown diamonds. We always advise visiting local jeweller or gem lab to understand more about your stone.
