Everything You Need to Know About CVD Diamonds. 

As lab grown diamonds become common, certain terms are equally gaining traction. CVD diamonds are among search words. If you are one of those who is concerned about the effect diamond mining has on the environment but you still love the beauty of diamonds and would like to own or invest in them, then knowing more about CVD diamonds is important.

In this article, you will get all the information you need to know about them. We shall start from the basics like what they are and then progress to topics like where to find them and much more.

What are CVD Diamonds?

CVD diamonds are a type of man-made diamond. The acronym CVD stands for Chemical Vapor Deposition. They get their name from the process that they go through to be created.

Despite being man-made, these diamonds have every characteristic of natural diamonds. That is because the CVD process is a replication of what nature does through hundreds of years to create natural diamonds.

CVD rough diamonds are created by using a small piece of a diamond called a seed which is placed into a machine. This machine contains a chamber that is heated to temperatures as high as 800 degrees centigrade. Next, carbon gas is pumped into the chamber. A chemical process results from this and the gas will attach itself to the seed diamond, causing it to grow into a bigger diamond.

Though when explained here it may seem very easy to grow diamonds using the CVD method, it is a complex process that needs expert manipulation to ensure pure diamonds are formed.

CVD rough diamonds are so much like the natural diamond that even expert gemologists require specialized tools to tell them apart.

You should also know that the other type of lab grown diamond is called HPHT (High-Pressure High-Temperature diamonds)

CVD Diamond Price

One of the driving forces behind the demand for CVD diamonds is their price. Despite remaining precious stones of high value, you would pay much less for them than for natural diamonds. For many shoppers, it is a case of getting more for less. The price of CVD diamonds can be between 40 and 60 percent less than natural diamonds.

When you understand the processes involved in mining diamonds and finally getting them to the market, it becomes clear why they are priced higher than those made in a lab by experts in the field.

The price however may vary according to the manufacturer. But, no doubt, what you would pay for the same carat weight of a natural diamond will be more than what you pay for LGD diamonds.

For actual prices, you need to contact sellers and get their quotes for whatever you need.

CVD Diamond Machines 

CVD diamond machines are probably the most expensive investment manufacturers have to make. The technology used to make the diamonds is not readily available to many people. Not all machines on the market will do an excellent job.

There is still a lot of research being carried out to improve the machines. Aspects such as how fast they grow the diamonds and the amount of energy used are still being perfected. However, many machine manufacturers have sufficient technology to meet the demand for diamonds grown in a laboratory.

Most makers of CVD diamond-making machines do not share the secrets about the design of their machines and the technology is patented so that they can continue to keep a hold on the market.

Anyone hoping to invest in the manufacture of LGD needs to find a maker of these machines and purchase them. In most cases, they also have to be installed in the lab by the makers.

Even then, the machines require expert technicians to handle the manufacturing process. Making diamonds using this technology is not like operating a coffee machine. Training and experience are needed.

CVD Diamond Machine Prices in India

Manufacturers of CVD diamond machines will have varying prices in India. Price can be determined by the capacity of the machine and its quality. It is important to have a discussion with the manufacturer about the machine that is being sold and how much it would cost to purchase one that meets your demand.


Even though natural diamonds still have more popularity than CVD diamonds, economists are certain that these eco-friendly gemstones will take up more market share in the coming years. With information like this available to more people, sales of the diamonds will step up.
