Disreputable companies are spreading misinformation  about the methods of growing diamonds and the superiority of one over the other: which is better or worse, CVD or HPHT. As you might have already noticed and wondered, the information coming from these companies and media outlets can be extremely contradicting when it comes to the topic of CVD vs HPHT diamonds. 

Why does the information differ when coming from different companies?

Simply put, this is due to these companies trying to push an agenda; they will say whatever benefits them the most. For example, we found a company in Melbourne, Australia, that loudly preach to their customers that CVD is the best and advises them to avoid buying HPHT. While another company in the USA tells their customers, that HPHT is the best, advocating against purchasing CVD diamonds. The reality is they are both deceiving their customers with misleading and often false, statements. Both CVD or HPHT technologies can produce any colour, clarity, and size, from the unsellable to faultless diamonds. What is happening behind the scenes, is that each of their suppliers, the labs creating the diamonds, is giving them a better deal, and sometimes pressuring, on CVD diamonds but not HPHT ones and vice versa. Therefore, they push the one that yields them the most profit while moving the most stock, and they will say whatever they need to say to keep it that way.

WHAT IS THE DIFFERENCE BETWEEN HPHT AND CVD?

When comparing CVD vs HPHT diamonds, there is absolutely no difference other than the process used to create them. You will not be able to tell the difference between HPHT vs CVD diamonds. Both methods are capable of producing the full range and quality of real diamonds that are optically, chemically, and physically identical to earth-grown diamonds.
We could dive deep into the technicalities of each method, detailing all the difference in the production process, but we believe it’s a waste of time at best and confuses and misleads people at worst. Instead, we prefer to provide you with practical and easy to follow reliable advice. As you are aware, each and every one of our lab-grown diamonds are industry certified by leading certifiers, therefore when choosing your diamond, solely focus on trying and go for as high of colour and size as your budget allows it. Additionally, when it comes to clarity, try to go for SI1 and above, with the exception of emerald cuts, where we recommend going for VS2 and above. By following those two simple guidelines we guarantee you will be happy with your choice, regardless of whether the production method was CVD or HTPT, since, as we’ve already discussed, it will make absolutely no difference to you.

Real facts:

  • CVD and HPHT can produce D colours
  • HPHT on average yields higher colours than CVD
  • CVD on average yields higher clarities than HPHT
  • HPHT and CVD can produce VVS1 and FL
  • Most diamonds under 1:00ct are HPHT due to costs effectiveness
