Many misconceptions are floating around about the two different methods of producing lab grown diamonds, often spread out of malicious intentions. All of them boil down to the question: which is better, CVD or HPHT? However, companies and media outlets are promoting conflicting information regarding CVD diamonds vs HPHT diamonds resulting in a sea of marketing material that is chaotic and inconsistent.

Why does the information differ within the industry from different companies?

It is not surprising that the information varies from article to article because companies are trying to push their own agenda. To construct a specific narrative, they cherry-pick information and write what supports their agenda. We recently encountered a global company that confidently proclaimed to its customers that CVD is superior to HPHT in terms of diamond growth. A USA-based company, by contrast, is promoting HPHT as the better method and urging customers against CVDs. In reality, both of these companies are misleading their respective customers with selective truths and a healthy dose of lies in the name of profit.

In the end, CVD and HPHT can produce diamonds with a wide range of colours, clarity, and size, from worthless and unmarketable ones to stunningly flawless ones. There is, however, a tug-of-war behind the scenes among the suppliers and the labs making the diamonds as to which method will yield them the most profit and move the most stock. They will say whatever is necessary to promote their method. For instance, a supplier may be pressuring their customers to buy CVD diamonds and not HPHT diamonds.

What Is The Difference Between Cvd And Hpht?

If you are a layman or customer looking for information about CVD or HPHT, there is absolutely no difference other than the process used to manufacture them. Either method produces a diamond with the same optical, chemical, and physical properties as a genuine diamond formed inside the earth. HPHT diamonds and CVD diamonds cannot be distinguished no matter how hard you or anyone else tries.
Although we could delve into detail about each method and highlight its differences, many experts in this field believe that it is pointless to waste everyone's time doing so. As an alternative, we will offer you practical and easy-to-follow advice based on our years of experience in the field.
Our advice is simple: all our lab grown diamonds are certified by leading certifiers; therefore, when choosing your diamond, be sure to focus solely on getting the maximum value for your money. Choose the largest stone within your price range while keeping the colour grade as close to D or E as possible. When it comes to clarity, you need to ensure it is eye-clean by choosing SI1 and above. In the case of emerald cuts, we recommend choosing VS2 or higher. Following those two simple guidelines will ensure that you are making the right choice. The way the diamonds were grown does not matter to you, so whether they were CVD or HTPT, you are bound to be happy with your choice.
For related search terms for similar articles, you can use any of the following search terms: HPHT vs CVD, CVD vs HPHT, CVD vs HPHT diamonds and HPHT diamond vs CVD.

Here are the real facts:

  • The HPHT and CVD processes are both capable of producing D colours
  • Compared to CVD, HPHT yields more diamonds with higher colour grades
  • CVD on average, yields higher clarities than HPHT
  • HPHT and CVD can produce VVS1 and FL
  • Most lab diamonds under 1:00ct are HPHT due to costs effectiveness

FAQ'S

• Are lab grown diamonds real?

Without question, lab grown diamonds are genuine diamonds. They are produced using the same chemical and physical processes found in nature, but under controlled laboratory conditions, where a diamond crystal seed is gradually expanded with additional carbon atoms. From a scientific standpoint, lab grown diamonds are chemically, physically, and optically identical to mined diamonds, and are thus considered authentic diamonds. The leading diamond authorities, IGI and GIA, evaluate lab made diamonds according to the same scale and methodology used to grade mined diamonds, further confirming their legitimacy.

• How much cheaper are lab diamonds?

Lab grown diamonds are consistently more affordable than diamonds mined from the earth. The extent of the price difference is influenced by several factors such as the diamond's size, quality, and specific type, but on average, lab made diamonds in New Zealand can cost around 75% less than mined diamonds. This is due to the lower cost of producing rough lab grown diamonds compared to the expense of mining and extracting rough mined diamonds from the earth. However, both lab grown and mined diamonds must undergo the same processes, including cutting, polishing, and certification, to become retail-ready, regardless of their origin. For instance, you can save significantly by opting for a lab grown diamond over a mined diamond. A mined diamond may cost $10,000, while an equivalent lab grown diamond might only cost $2,500.

• Do lab diamonds test as diamonds?

Lab grown and mined diamonds are indistinguishable from each other. The same testing methods used to examine mined diamonds are also applied to lab grown diamonds. Both diamonds are chemically, physically, and optically identical, and display the same attributes and features when tested. These characteristics include hardness, refractive index, thermal conductivity, and other distinguishing characteristics of diamonds, regardless of whether they are mined or man made.

• Do lab grown diamonds have inclusions?

Inclusions can be found in both lab grown and mined diamonds. These are mined flaws that are typically present within diamonds. These imperfections come in various forms, including small bubbles or carbon deposits trapped inside the diamond during its formation. In the same way as mined diamonds, most lab grown diamonds have inclusions, and only a few become entirely flawless. For further details on diamond clarity, please refer to our 4Cs guide.

• Can I insure lab grown diamond rings?

Yes you can, it’s the same as insuring a mined diamond. You can obtain insurance for your lab grown diamond in NZ through almost any insurance as long as they insure jewellery. Typically, your insurance policy will cover the cost of replacing or repairing your ring in the event of loss, theft, or damage. It is important to read the terms of your insurance policy carefully to understand what is and is not covered.
