Types of Lab-grown Diamonds You Should Know

Lab-Grown Diamonds are real diamonds, the only difference is how they are obtained. While natural diamonds have to stay underground for eons, lab-grown diamonds are simply recreating nature under scientifically modified environments.

Another shocker is that Lab-grown diamonds are of distinct types. Shocker? Well, read on to find out. On the side, check out these quality Eco Lab Diamonds.

Types of Lab Grown Diamonds You Should Know

If you are part of the sixty-six million people seeking to cut costs and go easy on your wallet by purchasing lab-grown diamonds for your engagement, you should know they are of two distinct types.

But before that, a little understanding of what Lab-grown diamonds seems needed

What Are Lab Grown Diamonds

Lab-Grown Diamonds are a perfect imitation of those shiny stones created close to three billion years ago. This imitation is done through an industrial process in a controlled environment subjecting carbon atoms to the same degree of heat and pressure through edge cutting technology.

The effect is the same, zero chemical, physical and optical differences

The two types of Lab-Grown Diamonds.

1. The HPHT growing Method

This was the first method of creating lab-grown diamonds. These lab-grown diamonds were created for industrial purposes in the year 1954. This mining method is done by ;

  • Placing diamond seed into a high-pressure chamber consisting of flux and graphite powder.
  • The chamber is then placed into a reactor and engulfed by anvils made out of steel
  • The Chamber is closed, locked and then, High pressure from the anvils and High Temperature is applied to the diamond seed. Hence the name, (HPHT).
  • The graphite dissolves into the metal and this causes the carbon atoms to crystalize on the diamond seed
  • The diamond is then shaped, cut and polished, and voila

2. The Chemical Vapor Deposition METHOD (CVD)

This method of growing synthetic diamonds has been in existence since the ’50s.  This is the most popular method of growing diamonds in a controlled environment. It is a highly practical and advanced method compared to the HPHT method of growing diamonds.

Diamonds grown through the CVD method do not only include diamo9nd seeds and high temperature, but there are other factors involved such as low chambers to mimic the earth, gases, and of course microwave beams to mimic the elements.

CVD grown diamonds are grown by

  • Placing thin diamond plates in a chamber
  • Sealing up the chamber and increasing temperature
  • A vacuum is created and then methane gas is released into it
  • Almost immediately, the glass is blasted by a microwave beam. This helps to release carbon atoms from the gas.
  • The carbon atoms begin to attach themselves to the thin plate in layers turning into our valuable stone
  • The diamond is then cut, shaped, polished, and weighed.

And those are the two types of lab-grown diamonds there are HPHT diamonds and CVD diamonds.


Lab-grown diamonds of HPHT or CVD, although called are entirely identical to the real deal so you can get one cut either as regular jewelry if you are that rich or even opt for one as an engagement ring
