Companies are spreading misinformation  about which method of growing diamonds is better, and which is worse. As you might have already noticed the information coming from different companies could be extremely contradicting. 

Why does the information differ when coming from different companies?

This is due to companies trying to push what benefits them the most. For example, we found a company in Melbourne, Australia that tells all their customers that CVD is the best and advises them to avoid buying HPHT. While another company in the USA tells its customers that HPHT is the best advocating against CVD. The reality is they are both deceiving their customers with false statements. Both technologies can produce any colour, clarity, and size. What is happening behind the scenes, is that each of their suppliers is giving them a better deal in CVD but not HPHT and vice versa. Therefore, they push the one that yields them the most profit.

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
