The name lab grown diamond or lab created diamond may compel you to think, are they real? And the answer is ‘Yes. These man-made diamonds are grown with the same temperature and pressure under which the natural diamonds are developed in the Earth’s crust. These diamonds comprise of actual carbon atoms. As these diamonds are made from the same material as natural ones, they possess the same chemical and optical features. If used in engagement rings, these diamonds can produce the same sparkle.

The production process of lab-grown diamonds

There are two ways through which lab-grown diamonds are created. First, through high pressure and high temperature (HPHT) and second through Chemical Vapor Deposition (CVD).


This process involves placing a small diamond seed into carbon, where it gets a temperature of around 1500°C and a pressure more than 70,000 times as that of sea level. At such an extreme condition, the carbon melts and formation of diamond happens around the seed. Once done, the diamond is cooled to get the crystal.


CVD happens inside vacuum plasma reactors. A diamond seed is kept inside the sealed chamber, and hydrocarbon gas is released in it. When the temperature rises up to 800°C, the ionization of gases happens through plasma. Powerful microwaves break the molecular bonds of gases and pure diamond deposits over the diamond plates, which later on crystallizes.

Reasons to Choose a Lab Created Diamond

Less expensive

When we talk about processes like cutting, polishing, and testing, both the natural and lab-grown diamonds have the same cost. Natural diamonds involve lengthier supply chain processes as these are obtained through the mining process. While lab-grown diamonds forgo mining and thus saves the overall cost of labor. This makes lab-grown diamonds a wallet-friendly option for the customers without compromising on the quality of diamonds.


The entire mining process has a significant impact on the environment. Mining companies put their efforts to minimize this impact to save the environment. However, the mining process is avoided in lab-grown diamonds, and less energy is required to create them, as no digging is required to obtain the diamond.

Certification and Grading of Lab Diamonds

The same process is involved for grading and certification of lab created diamonds as that of natural one. These diamonds are sent to gem labs, and these labs give their grade depending upon the cut, color, clarity, and carat of diamond. Different gemologist gives a grade for each diamond, and the individual grades are analyzed to decide the final grade of a diamond.

This process is followed to obtain an unbiased grading system. However, it is possible to get a different grade for the same diamond not only from different labs but also from the same lab if sent for a second opinion.

Lab-Grown diamonds vs. Natural diamonds

It is hard to find any difference between lab-grown and natural diamonds. Both have the same fire, sparkle, and scintillation. Lab diamonds may contain trace elements, but this will never reflect in their appearance. The only way to differentiate two diamonds is through specialized equipment. Lab-grown diamonds come with a gem certification, which tells customers that they are lab-grown.

Bottom Line

Are you shifting your focus towards lab-grown diamonds? If yes, then purchase them without any hesitation. These mining free diamonds have the same chemical, physical, and optical properties as that of natural ones. These diamonds are more affordable as that of natural ones with the same size and quality. You can see the price difference between them at Diamond Hedge, they have the largest selection of lab-grown diamonds. It is the perfect choice and perfect gift to your loved one.
