Identify Man-Made CVD Synthetic Diamonds Education

Table of Contents

To identify man-made CVD synthetic diamonds was never easy. Lab-grown diamonds either produced by HPHT or chemical vapor 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 jeweler.

However, Lab-grown diamonds are getting really popular as they are very much identical to the natural diamonds. There is very few information available on the web. Below are some sure ways to identify lab-grown diamonds.

Kindly note: Cubic Zirconia (CZ), Moissanite and lab-grown diamonds are all different.

7 Tips to Identify man-made CVD synthetic diamonds

  • Use Microscope:  Keeping stone under the microscope, you can observe some characteristic strain patterns which differ from natural diamonds.
  • Use DiamondView Machine: DTC’s recently launched DiamondView machine. It is designed to detect synthetic diamond. CVD synthetic diamonds turn to strong red fluorescence under high-energy UV radiation in the DiamondView machine.CVD DIAMOND in Diamondview
  • 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.
  • 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.
  • 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.
  • 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 colors some of the most common are blue, yellow and white.

  1. hi there u can check cvd thorugh Uv by exposing them Long wave and Short wave one by one, if it shows Green color chances are high that they are synthetic.. or u can check minute mettalic inclusions in 100x microscope too..
    hope i add something..
    thanks for sharing your knowlwdge
    u can connect me on

    • Thanks, Anirudh for stopping by and adding your valuable comment. Yes, Exposing stone into long and short waves helps to identify synthetic diamonds. Also checking into a 10x microscope is a good idea, but is not ideal for an untrained person.

      Have a great day. 🙂

  2. thanx harsh for valuable information about CVD diamond identification. I am also in learning stage in diamond industry..

  3. Wonderful web site. Plenty of useful information here.
    I’m sending it to a few friends ans additionally sharing in delicious.
    And of course, thanks in your effort!
