Man Made Diamonds: The Process of Creating Them Using Chemical Vapor Deposition

In recent years, there has been a massive trend toward man-made diamonds. Man-made diamonds are no doubt the latest fashion statement in the world of fashion jewelry. The reason why this trend is taking place is that the entire diamond industry is losing its relevance. Natural diamonds have always ruled the jewelry industry, but the fact is that they are becoming costly and out of reach of everyone except the super-rich.


Diamonds are now being grown and refined in laboratories. Man-Made Diamonds are called superior quality diamonds due to their distinct qualities. Lab-made diamond is a diamond made by a production process, compared to natural diamond extracted from the earth by scientific processes. It is observed that lab-grown diamond contains very little difference compared to natural diamonds, and their quality is almost identical to that of natural diamonds. These man-made stones are known as HHT.

Another name for this type of diamond is sparkle diamonds or growth cells. This term is used for diamonds grown in large sizes in a controlled environment, usually in a chemical plant. It is observed that HHT diamonds are produced on a large scale and are therefore far more superior to other diamonds of similar weight and size. It is said that HHT diamonds produce ten times more sparkle as compared to other types of diamonds.

The third name for these stones is cold melt, and Man-made could melt. As the name indicates, this type of diamond is created by chemical vapor deposition. Chemical vapor deposition is a process where various chemicals are melted onto the surface of the target material. This melts a film of a particular material on the surface of the target material, which is later reflected and refracted through a tiny hole. Man-made cold melt is considered to be a superior class of diamond due to its exceptional properties.

The last type of diamond crystal is called growth cell diamond. It is formed by growing individual crystals on support. A growth cell can be made on an instrument in a laboratory. It is manufactured by adding different growth cell elements to a diamond crystal during heating.

The price of a man-made diamond depends upon the four Cs, i.e., cut, color, clarity, and carat. The cut of a man-made diamond refers to the proportions of the face of the diamond. A perfect cut diamond is rare and expensive. A good-cut diamond is less rare but not as expensive. A colorless diamond with high clarity and color is affordable.

On the other hand, lab-grown diamonds are far less expensive than their natural counterparts. In addition, man made diamonds are not as challenging to identify as lab-grown ones, which helps the buyer get a good quality stone without too much effort. The lab-created diamonds are also mined by professionals, unlike the rough earth mines populated by rough men who look for the vein.

Although the price of lab-created diamonds is a bit higher than the average one, they are more durable. They have a longer life and require little care and maintenance. So they are more affordable than natural diamonds.

Man made, lab-created diamonds are mainly used for paving, though they can be used in rings and earrings. However, they are usually used as a backing for drop earrings, stud earrings, and chandeliers. These stones are made using high-temperature methods like carbon crystallization at the High-Tech Laboratory. In addition, chemical vapor deposition and high-pressure direct bonding techniques are also used for the same purpose. The stones formed using these chemical vapor deposition and high-pressure direct bonding processes have excellent fire, scratch, and heat resistance properties.

Man made diamonds have excellent clarity and color, which cannot be found in nature. They are shiny, and they sparkle with all the colors of the rainbow. The diamonds formed this way have perfect cut, clarity, and color. Chemical vapor deposition makes it possible to obtain flawless, sparkling, and durable stones. During the process, the carbon atoms of the diamonds are vaporized, and they have left behind a solid diamond structure. There is a lot of research to learn how this can be utilized for other purposes.

This lab-created diamond method is much better than the traditional way of forming diamonds. The diamond crystal is heated to millions of degrees in the traditional method and then cooled down to thousands of degrees. The high temperatures and the considerable pressure used in this process destroy the carbon atoms’ hydrogen bonds. The result is very unstable diamonds that are vulnerable to cracks.
