CVD Diamond : Everything You Need To Know.

CVD diamond which is full-form is called Chemical Vapor Deposition. Many jewelers and diamond jewelry buyers do not know CVD Diamond and what it is called? And myth stuck in my mind without clear. Here you will get all the details about CVD diamonds or lab diamonds. Diamonds are the hardest natural substance on earth, and they are found in many places around the world. Natural diamonds are rare; that’s why they are expensive. But there is a way to make your diamonds using carbon dioxide (CO2). This article will discuss what you need to know about the CVD diamond manufacturing process and its benefits.


To understand how the CVD process works, let’s first look at CVD diamonds and how they are made.

What are CVD diamonds?

What are CVD diamonds

CVD diamond is simple to manufacture through the Chemical Vapour Deposition process inside a lab chamber. CVD process possible inside a laboratory chamber where use natural gas and methane will put into the lab chamber where diamond process and these two gas combination break down carbon seed and transform into crystal diamond. All of this process takes approximately 3 to 4 weeks around time. They use natural gas to make these CVD diamonds at high temperatures between 2000 and 3500 degrees Celsius.

Are CVD Diamonds Real?

CVD diamonds are commonly known as jewelry market synthetics or laboratory-grown diamonds. CVD diamonds are made inside a lab chamber with natural gas and carbon seed, just like a real diamond made on earth ground. That same process happens inside a lab under the observation of an expert.


If you compare real diamond with this lab-made diamond CVD, one has happened same chemical formation.


CVD diamonds’ brilliance, spark, value, and durability are the same as natural diamonds and look stunning fire when cut like a diamond stone for an engagement ring or other jewelry ornaments purpose. There is a simple understanding difference between CVD diamond and natural diamond: CVD-based diamonds are manufactured inside a lab chamber, and real diamond is mined from earth ground, but processes are faced both same.

How Long Does It Take For A Diamond To Form?

It is a most curious question asked by many, and the answer is only predictable for natural diamonds; billions to thousands of times have been taken from carbon to rough stone diamond from creation under the earth ground. But synthetic lab-grown one takes almost 4 weeks; this process is under the lab chamber without a flawless problem. There are two types of a procedure; one known is High-Pressure High Temperature or HPHT. The second method for creating lab diamonds is Chemical Vapor Deposition (CVD).

History of CVD diamonds

Why is CVD Diamond Cheaper than Mined Diamond?

The mined diamond stone is a natural diamond found below the earth’s ground. And natural diamonds are primarily found in Asia, Africa, and America continents countries, but natural mined diamonds take a lengthy procedure. Deep digging 50 to 500 feet from ground level surface costs a lot like machinery, labor, and permission granted from the government. But we talk about CVD diamonds as cheaper than mind diamonds, so there are CVD diamonds 30% cheaper than mined diamonds. 

How Are CVD Diamonds Made?

The CVD diamond growing process is relatively slow compared to other laboratory diamond growing processes, as the molecules move at a speed of around 0.1-10 microns, attaching themselves and forming a diamond film in almost an hour. Due to this method’s slow processing, mimicking or copying the authentic and natural way of diamond formation is hectic. Accordingly, it takes 4 weeks to grow a single crystal diamond using a diamond seed.

In CVD of diamonds,

  • A fragile “seed” is placed in a sealed chamber. The seed is often composed of deposit materials of carbon, fluorocarbons, silicon, filaments, etc.
  • The seed is subjected to high temperatures estimated at around 800 degrees Celsius.
  • A carbon-rich gas, usually a combination of natural and methane gases, is introduced inside the chamber. Here the carbon particles get ionized and undergo a molecular breakdown, and only the pure carbon particles settle on the diamond seed.
  • As the carbon particles combine and build-up, a more significant pure carbon component is formed. This newly formed component is identical to a naturally mined diamond in physical, chemical, and optical properties.

What are the benefits of CVD diamonds?

Natural diamonds are rare and adorable, but what if you get better than rare at your price? Yes, you read it right, BETTER than natural diamond.

There are many aspects where CVD diamonds are better than natural diamonds, like purity, price, and environmental effect.

  • Only 2% of mined diamonds are considered the purest diamond with no inclusions and dirt, but all CVD synthetic diamonds are IIA type, which means they have no impurities.
  • Don’t ever think that high price leads to better things because sometimes the best diamonds come at the least expense. That’s what happens with CVD diamonds; they cost ¼ times lesser than natural diamonds.
  • Are you guessing that natural diamonds, whose name itself includes “NATURE,” will never harm the environment? Then maybe you are misguided. CVD diamonds are eco-friendly, while mined diamonds are not.

Through this, you may get the interest to know more about the price of CVD diamond. That’s what our next topic explained.

Are all Lab Grown diamonds CVD Diamonds?

Diamonds that are grown in laboratories are synthesized using a variety of techniques. CVD or Chemical Vapor Deposition is ONE of the ways through which laboratories manufacture diamonds. Traditionally, HPHT was the method through which researchers found that diamonds could be synthesized with the help of a diamond anvil.

CVD is comparatively a new method that evolved in the decades following the 1980s. Since then, manufacturing laboratory diamonds has been a relatively popular way to avoid exhaustive resources and rigorous machinery. Even though CVD consumes an elaborate procedure followed by a considerable time, it is still better preferred by Lab Diamond companies, Finegrown Diamonds itself included.

Other methods apart from the HPHT process and CVD are reasonably new to the diamond industry and almost less used by any manufacturing unit.

How To Clean CVD Diamonds?

Since diamonds are one of the most durable substances on earth, that doesn’t mean they do not need maintenance. Diamond and diamond jewelry requires some care and cleaning to sustain their quality and spark.

  • Where you put a diamond is most important. Always keep your CVD diamond in a given box or zip lock bag to keep it safe from any unpredictable accident.
  • Periodic professional cleaning can make your diamond shine more.
  • Try not to use the ultrasonic cleaner as much as possible, as it will harm the metal of your jewelry; hence the chances of losing your diamond will increase.
  • Permanently remove your jewelry before going for any heavy household cleaning or sports activities.

Wear your jewelry after applying your skin product to keep your jewelry safe from any external chemicals.

CVD Diamonds Price

The price of CVD diamonds is relatively low compared to mined diamonds. The reason is not so straightforward, natural diamonds are mined, and it’s associated with colossal mining costs and hence exceedingly pricey; only one of the reasons. To extract a single diamond from the depths of the earth’s mantle requires a load of human and material resources. This exhausts the resources and leads to a substantial ecological loss. On the other hand, CVD diamonds are produced with the help of technology and pure carbon atoms devoiding chemical impurities. (carbon is an element present in everything in and around us).

Buy CVD-based lab-grown diamond or colored lab-grown from a trusted manufacturer and wholesaler company like finegrown diamond. Finegrown diamonds is also one of the certification providers; finegrown diamonds can directly sell its diamonds to customers with the best offer and trusted shipping partner. And ordinary people get relief from paying extra to the double-dealing and mid-man.

Lab-grown CVD diamonds are almost 20% to 40% cheaper than their natural counterparts of the same grade;

CVD diamonds are thus, not only eco-friendly and sustainable but also economical. Switching to CVD diamonds is a wise decision and a step towards a changed attitude concerning our planet and its sustainable future. You can buy a near-colorless CVD lab diamond for the price of a lower colored (I, J, K) colored earth mined diamond.

Inquiry CVD Diamond

The authenticity of CVD diamonds 

CVD diamonds are man-made in laboratories under controlled conditions and temperatures. Hence, it is often assumed that they would turn out to be looking flawless, devoid of inclusions, and picture-perfect. However, that is not the case. 

Since CVD diamonds require the same production process as one involved in the formation of natural diamonds, they are not perfect in appearance and structure and may have chemical impurities. The Lab growing diamond also has certain imperfections similar to those found in natural diamonds. On the brighter side, this makes them more similar to natural diamonds. The inclusions in a diamond are natural and, preferably, make each diamond different from its counterparts.

After CVD lab diamonds have been manufactured in the Laboratory, they undergo the same cutting and polishing process as followed for natural diamonds. Their imperfections are removed or reduced to the nearest possible extent. If the imperfection is on the table or edges, it can easily be removed, but if the flaw is inside, then it is inclusive of the diamond. 

The clarity, cut, color, and carat of the CVD diamond is measured and properly certified by professionally qualified diamond certification laboratories like IGI, GIA, AGS to protect the diamond’s authenticity, keeping its real value intact.

18 Frequently Asked Questions(FAQ) About CVD Diamonds

Completely not, they both are different from each other. CVD diamonds hold elements like carbon atoms that make CVD diamond durable and similar to real diamonds, not with the CZ, which does not contain any carbon and is comparatively weaker than CVD diamonds.

Beside their origin, nothing is different between natural and CVD diamonds. By physical, optical, chemical, or thermal CVD diamonds are the same as natural diamonds. Also, CVD is the purest type of diamond, as it is also called IIa diamond.

All diamonds are classified into two types II and IIa. II are the types of diamonds that hold some impurities in them, and IIa are the types that include diamonds considered as no impurities or inclusion in them. Even in natural diamonds, only 1-2 % of diamonds come in IIa types. But all CVD diamonds are IIa diamonds because of their controlled method process of growing.

Our scientists have researched for many years how diamonds are created deep in the earth. As a result, we get the secret of the diamond making process. And now, we can grow diamonds in laboratories through two methods known as CVD (Chemical Vapor Deposition) and HPHT (High-Temperature High Pressure) in just three weeks.

HPHT diamonds are high in price, and the resulting diamonds of HPHT are yellowish and brownish because of their high pressure and high-temperature method. On the other hand, CVD diamonds are comparatively less in price and good quality as it needs small and inexpensive equipment.

The process of growing a CVD diamond is unique. In this process, a seed of diamond is placed under a closed plasma chamber with a high temperature of 800 °C. Then in the container, rich-carbon gases are released. The gases are ionized and start discharging their molecular bonds, which let the pure carbon tie-up with the diamond seed. With time carbon takes its shape by making an atomic carbon bond. By this, the thin diamond seed became a real diamond.

CVD diamonds are grown in a laboratory with less equipment and supplements. While in natural diamonds, the process of mining and transportation takes many costs comparatively. Hence, the CVD diamonds are more affordable than natural diamonds.

Alike natural diamonds CVD diamonds also have inclusions that affect its grading.

Grading of CVD diamond depends on its 4 C’s; color, carat, clarity, and cut. Same as natural diamond CVD diamonds also provides a certificate of grading.

Yes, All lab-grown diamonds are graded by reputable non-profit gemological laboratories, like IGI, GCAL, GIA, and EGL.

Yes, All lab-grown diamonds are graded by reputable non-profit gemological laboratories, like IGI, GCAL, GIA, and EGL.

Shifting to CVD diamonds from natural diamonds brings many positive impacts to our environment as CVD diamonds are way more eco-friendly than natural diamonds. CVD holds many benefits; some of them are Ethical, social, and conflict-free.

NO, CVD or lab-grown diamond never fades its color or become cloudy with time as it holds the same elements as mine diamonds.

By naked eyes, it is IMPOSSIBLE. CVD diamonds are too similar to natural diamonds that even the experts in diamond fields get sometimes confused about which one is real. By which GIA specially launched a hi-tech machine which detects the lab-created diamonds.
