What's Synthetic diamond?
A synthetic diamond (also known as a laboratory-grown diamond, a cultured diamond, or a cultivated diamond) is a diamond produced by a controlled process, as contrasted with a natural diamond created by geological processes or an imitation diamond made of non-diamond material that appears similar to a diamond. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). While the term synthetic may sometimes be associated by consumers with imitation products, synthetic diamonds are made of the same material as natural diamonds—pure carbon, crystallized in an isotropic 3D form.
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.
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.

FAQ of Lab Diamond Stones:
Q1:Are lab grown diamonds CVD?
A:Simply put, some diamonds are mined, and some are lab grown diamonds. CVD diamonds are man-made. Unlike natural diamonds, which take billions of years to form deep beneath the Earth's surface, CVD diamonds are grown in labs. CVD stands for chemical vapor deposition, the process used to create lab grown diamonds.
Q2:Which lab grown diamond is better CVD or HPHT?
A:Generally, the CVD process produces lab grown diamonds of a high clarity and colour but it's good to finish the process with HPHT to bring out the best in the diamond. The CVD process is also less energy intensive, producing more competitively priced diamonds.
Q3:What does CVD stand for in lab grown diamonds?
A: Chemical Vapor Deposition: Colorless synthetic diamonds produced by Chemical Vapor Deposition (CVD) are becoming more common in the market.
Q4:How can you tell if a diamond is CVD?
A:You can identify CVD diamonds fairly simply. They have a unique strain pattern that doesn't resemble that of natural diamonds and strong red fluorescence. In addition, they lack the typical “Cape Line” at 415 nm on their absorption spectrum. Instead, they present a strong line at 737 nm.
Q5:Are CVD diamonds cheaper than natural diamonds?
How Much Do CVD Diamonds Cost. CVD diamonds usually cost between 20% and 30% less than naturally sourced diamonds. You could pay the same amount of money for a 2-carat CVD as you would for a 1.5-carat mined diamond.
