lab-grown diamond rings in Hatton Garden


| Daniel Brisk

The ongoing debate surrounding HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition) diamonds has created confusion and misinformation in the industry. Different companies seem to advocate for one method over the other, leaving consumers wondering which is truly superior. However, it's important to understand that the conflicting information stems from each company's self-interest rather than objective facts.

Companies may promote CVD diamonds as the best option while discouraging the purchase of HPHT diamonds, and vice versa. The truth is, they are simply pushing the method that benefits their own bottom line. The choice between CVD and HPHT is often determined by the deals and incentives offered by their respective suppliers. Their priority is profit, not necessarily providing accurate information to customers.

So, what is the actual difference between CVD and HPHT diamonds? When it comes to the diamonds themselves, there is no discernible difference between the two. Optically, chemically, and physically, both methods produce diamonds that are indistinguishable from naturally grown ones. While we could delve into the technicalities of each production process, we believe it is more practical to offer reliable advice.

At Regal, we focus on providing industry-certified lab-grown diamonds from reputable sources. Our recommendation is simple: choose a diamond based on its colour and size, aiming for the highest quality that fits your budget. For clarity, consider VS2 and above, except for emerald cuts, where we suggest going for VS1 and above. By following these guidelines, you can be confident in your choice, regardless of whether the diamond was created through CVD or HPHT.

Let's clarify some real facts:

  • Both HPHT and CVD can produce diamonds in D colour.
  • HPHT generally yields higher colours on average compared to CVD.
  • CVD typically yields higher clarities on average compared to HPHT.
  • Both methods can produce diamonds in VVS1 and Flawless (FL) clarities.
  • Diamonds under 1.00ct are often HPHT due to cost-effectiveness.
