Unleash the Methods of Lab-Grown Diamonds and their Differences

CUMMING, Ga. - Jan. 21, 2021 - PRLog -- If you are searching for a lab-grown diamond for gifting your partner or already own a lab-grown diamond, you may be wondering how they are made. Two processes can make a lab-grown diamond. An HPHT Diamond manufacturer can explain what it means and the difference between HPHT CVD Diamonds.

The HPHT Method – High-Pressure High Temperature

The HPHT method is the original method. Diamond manufacturer have been using this method of creating lab-grown diamonds since the 1950s. This method can enhance the color of diamonds like green, pink, blue, or yellow, known as Emerald, Ruby, Sapphire, and Canary, respectively. A small diamond seed is placed in carbon if you grow an HPHT diamond. These diamonds are made of carbon element and exposed to extreme heat and pressure. Such a method is naturally seen growing underground by the earth, so they are termed natural diamonds.

The lab-grown diamonds grow at 2,000 degrees Fahrenheit and about 1.5 million PSI pressure. The carbon melts and forms a diamond around that seed. Once it is cooled down, a diamond is formed. While forming a diamond, they are exposed to nitrogen, so they have a yellowish hue. They have metallic inclusions that help scientists identify the diamond as a lab-grown diamond because naturally formed diamonds do not capture metal during formation. A rough HPHT diamond formed differently than a rough CVD diamond.

The CVD Method – Chemical Vapor Deposition

The Lab-grown Diamond Companies had started using the CVD method since the 1980s, making a revolution than the HPHT method. This process uses less pressure than the HPHT method and imitates how diamonds form in gas clouds. Unlike HPHT, in this method, a diamond seed is placed in a vacuum chamber. Heated at nearly 1500 degrees Fahrenheit, this chamber is filled with carbon-rich gases. This process produces Type IIA diamonds that are found rare. Type IIA diamonds are chemically pure diamonds, and they lack nitrogen impurities. CVD diamonds are not magnetic like HPHT diamonds.

There is a thin line between HPHT and CVD process for making diamonds. Both methods are beautiful in their way and create beautiful diamonds. These methods create diamonds that are optically and chemically, similar to earth-grown diamonds that cannot be identified with the naked eye.
