Welcome to Excellent Corporation
Here We will discuss about TWO TYPE of Lab Grown Diamonds CVD TYPE2A Diamond and HPHT TYPE2 Also we will discuss about Some Major Differences about These Two Types. Lab Grown Diamond Created in Lab With Chemical Vapour Deposition is Known as CVD, TYPE2A diamond. Lab Grown Diamond Created in Lab with High pressure and High temperature method which Known as HPHT TYPE2 Diamond. Both have same look, as natural diamond, everything is same. But because of difference in the making process, both react differently on diamond tester. CVD TYPE2A Diamond will show as Diamond on Diamond tester, and HPHT TYPE2 Will not show as diamond on diamond tester. this is major difference.
Just For an Example, if we will take two stones of G Color VVS Clarity, One is CVD and another is HPHT, We can not recognize with naked eyes which one is CVD and which one is HPHT. With the diamond tester we can check it. In Loose Non Certified Diamond As per the requirement, some people only want CVD, they don’t want HPHT, in this case We have to check with Diamond tester and we can make sure about what we are delivering , its CVD or HPHT. Well, Another Major Difference is about availability in Better Color in Small Diamonds. in CVD TYPE2A Diamond, there D Color is not available in small sizes Like Star Melee etc. But in HPHT you can get all better color in small sizes also.
For an Example, if you want to buy 0.01ct Size Diamonds in CVD, you will Get the color Like GHI , DEF Will not be available there. But if you will go with HPHT, there you will get DEF color also in this small size. Other all things are same, like clarity, cut and more, all same in both. If you want D color 1ct of any clarity, will available only in HPHT. In CVD we can get the best color as E Usually, D Will not available in CVD. Both type of diamonds can be certified by IGI and HRD and other lab In the certification, you will get clearly mentioned the process with diamond made. Like in the Certificate of CVD, there It will be clearly mentioned that this Laboratory Grown Diamond made with Chemical Vapour Deposition CVD TYPE2A in Comments. and other side in the certificate of HPHT, there is the same, process mentioned. so this is the main things and differences about CVD and HPHT both type ofLab Grown Diamonds.
