Do Lab-Grown Diamonds Have Flaws?

The short and quick answer is an absolute no. Lab-grown diamonds have similar imperfections to natural mined diamonds. This is because natural mined diamonds and lab-created diamonds have to undergo the same process of formation. There can be many variables that can occur during the process, both naturally as well as in the lab. This leads to imperfections in the diamond structure. The imperfections created in lab-created or mined diamonds are graded as per 4C’s cut, clarity, carat weight, and clarity.

How are lab-created diamonds formed?

Lab-created diamonds and mined diamonds are both optically, chemically, and physically the same, with their origin as the only point of difference. While natural diamonds are found under the earth's crust in the presence of carbon dioxide, which comprises carbon atoms and is formed due to extreme pressure and high temperature. Lab-created diamonds are made in the laboratory to speed up and replicate the process in which natural diamonds are formed.

What type of flaws do lab-made diamonds contain? 

Lab-made diamonds have similar flaws to man-made diamonds that are graded as per 4C’s cut, carat weight, clarity, and color. Generally, there are four determining factors that influence the price as well as the quality of lab-created diamonds as well as natural diamonds. These four important factors are as follows.


Flawless diamonds technically exist however they are extremely rare. By the flawless diamond, you refer to the clarity of the stone. Diamonds have inclusions but are formed when diamonds are grown too fast. A Flawless diamond comes without any inclusions. The rarity nature of flawless lab-grown diamonds and mined diamonds makes them one of the most demanded stone. Such inclusions mainly occur when a diamond stone is grown quickly within the laboratory and 200 kilometers under the earth's crust. A flawless clarity diamond is free from all types of inclusions. A diamond that contains certain inclusions shows imperfections. You can opt for is SI1 clarity diamond, where inclusions will be completely invisible to your eye.


Diamond, which is flawless in its clarity, can also be imperfect in terms of color. The Color of Mined and lab-grown diamonds are graded at a scale of D to Z, where the letter D stands for colorless diamonds and appears to be the brightest and whitest ones. Trace elements are present in both types of diamonds, making them appear brownish or yellowish. The lowest color grade diamond has more warmth. D Flawless means the lab-grown diamond is made as white as possible and comes with no imperfections.


A diamond cut is a measurement of how the stone can refract and reflect light, creating the ability to sparkle more. Every lab-grown diamond's cut grade is unique since they are individually cut and precisely mapped as per the highest standards. As a result, the diamond has an excellent cut grade and typically sparkle more than the lowest cut grade. You should opt for diamonds with good cut grades to ensure a flawless and glistening diamond.

Carat Weight

Large diamonds, both in the laboratory and in their nature, take a long time to form, so they are more expensive and rare in nature. Small diamonds will take certain weeks, whereas 3 CT lab-grown diamonds will take a month to form. The best thing about buying lab-grown diamonds is that you can afford bigger diamonds within your budget as one carat diamond comes at the same price as a natural diamond with 0. 5ct.


Fluorescence is another perfection that occurs mainly in natural and not lab-created diamonds. If you want to know whether your diamond is flawless, you can get a diamond certificate from New World Diamonds to understand the 4Cs. The excellent clarity grade of diamonds is rare and unique.
