What Is The Difference CVD Diamonds Vs Lab Diamonds?

In the diamond industry, there are two main types of diamonds used in jewelry and other products. One type is made synthetically (lab-created), while the other type is mined from the ground naturally (natural or earth-mined diamonds). Lab-created diamonds, also called chemical vapour deposition (CVD) diamonds or cultured diamonds, have been produced commercially since the 1980s and are now readily available in most markets around the world at prices comparable to natural or earth-mined diamonds. Before we dive into their differences, here’s some background information on each one.


Lab diamonds are created artificially in a lab by exposing carbon to extreme heat and pressure. In contrast, CVD diamonds are created naturally by deep-sea volcanic eruptions.

Lab diamonds are often cheaper because they’re less scarce and easier to produce than CVD diamonds, but that doesn’t mean they’re better. The process of creating them can be detrimental to the environment, which is why many people prefer buying CVD diamonds instead of lab-created stones.

A diamond’s clarity is determined by how many flaws it has on its surface. The fewer flaws there are, the clearer it will be. Lab-created stones have a lower clarity grade because they tend to have more imperfections than natural stones do.

The Pros And Cons Of CVD Diamonds

The biggest difference between CVD diamonds and lab-created diamonds is that lab-created stones are created in a laboratory under controlled conditions whereas CVD diamonds are created by nature. However, there are a few other key distinctions to consider. CVD gems have a slightly lower level of hardness than their lab counterparts, but their clarity is just as high. They also have less brilliance than lab-created gems because they’re not cut to reflect light as well. And unlike lab-produced gems, which can be made from any type of diamond or colourless stone, CVD stones are only white. In addition, it takes more time for CVD gems to grow compared to lab-made ones. There’s one more major distinction: price. In some cases, a single carat of lab-made diamond may cost about three times as much as a carat of CVD diamond with similar qualities.

The Pros And Cons Of Lab-Grown Diamonds

Lab-grown diamonds are a beautiful alternative to natural diamonds. They are grown in a lab, which is why they’re called lab-grown or cultured diamonds. Compared to mined diamonds, they’re much more affordable and environmentally friendly. One downside is that because they’re man-made, some people find them less valuable than natural diamonds. That being said, those who are interested in buying CVD diamond jewellery should know what the difference between these two types of stones is so they can make an educated decision when it comes time to buy one for themselves or their significant other. The first thing to understand is that while both types of diamonds are created by humans, CVD diamonds are not as rare as traditional lab-grown diamonds. The second thing you need to know is that this means that the value will be different, with a bigger price tag for traditional diamond jewellery. The third thing you’ll want to understand about CVD diamond jewellery is how durable it is. It’s very tough and not likely to break easily as some mined stones may be.

So, Which One Should You Choose?

The choice between lab diamonds and CVD diamonds can be difficult, but it should be made easier by knowing what each type of diamond is. The differences between these two types of diamonds are not only in their origins but also in their prices. If you’re looking for a diamond that is affordable and has a long-lasting shine then you might want to consider a lab diamond. However, if your budget allows for it, then CVD diamonds are great because they are rare and cost more per carat. You may find yourself choosing between a lab diamond or a CVD diamond depending on what features you want your stone to have. For example, if colourless stones with high clarity are important then an expensive CVD would be worth investing in. But if you need something that won’t lose its lustre over time, then a lab diamond might be better.
