7 Certifications of Lab-Grown Diamonds Available In The Market

 Lab grown diamonds are precious stones that are developed artificially using technology that simulates the natural diamond-growing process. While many people are of the opinion that these diamonds are not genuine, this statement is completely false. Since lab-grown diamonds have the same physical and chemical properties as naturally-found ones, they too are considered to be real.


This recent breakthrough in the diamond industry has led to many switching over to lab-grown diamonds in the recent past. Apart from looking exactly like real diamonds, they are also significantly more affordable, making them a go-to option for many.


Why Do You Need To Get A Certification For Your Lab-Grown Diamonds?


As mentioned above, lab-grown diamonds have become very popular. This sudden demand for these gems has led to several sellers claiming that a gem is a lab-grown diamond. Hence, it becomes crucial for you to attain a certificate that proves the authenticity of your diamond.


Today, there are a plethora of leading diamond grading laboratories that will provide a certification along with your precious stone. These certifications are documents that possess details about the diamond’s characteristics. Your diamond will be assessed using advanced tools by trained professionals.


They will provide you with all the details about your diamond, such as color, clarity, length, and width, which will certify its purity and authenticity. Hence, it’s crucial that you buy your lab-grown diamonds at places that will offer you certificates for your gems from accredited organizations.


Types Of Certifications Of Lab-Grown Diamonds Available In The Market


There are a handful of certifications of lab-grown diamonds that are available, and they are as follows:

1 The International Gemological Institute (IGI)

This Belgian institute is one of the best certifications for lab-grown diamonds. Not only do they accredit lab-grown diamonds, but they also certify natural ones too. All of their professionals are highly trained with years of grading experience and come with a gemological background.


They study the diamonds in-depth and offer grades for parameters like color and clarity. They help you compare diamonds and ensure you get exactly what you paid for. So, when you purchase a diamond that is certified by IGI, you can trust that the diamond is real and it is of the same quality that is claimed by the seller or manufacturer.

2 The Gemological Institute of America (GIA)

If there’s one respected and renowned diamond certifier for several decades now, it’s GIA. Not only are they consistent with their grading, but lab-grown diamonds are tested under the same processes of grading as natural diamonds. This organization tests inclusions, fluorescence, and phosphorescence, making them a trusted body in its field of expertise.


Their grading report also includes an assessment of the diamond’s 4Cs, which is color, clarity, cut, and carat weight. Lastly, customers will also get a plotted diagram that illustrates the clarity characteristics as well as receive a graphic representation of the diamond’s proportions.

3 The American Gem Society (AGS)

AGS is a reliable laboratory that offers a unique grading system. They have been around for a while now and have made it easier and safer to buy jewelry of any kind.


For customers who are interested in receiving an in-depth report about the cut, quality, and light performance of the diamond, an AGS report provides a far better analysis than the others mentioned above. And most importantly, they also use the highest standards of ethics and integrity while assessing any and every diamond.

4 Gem Certification & Assurance Lab (GCAL)

A report from GCAL serves as verification of your diamond’s quality. They utilize a unique quality control procedure to grade the color, cut, carat weight, and clarity of diamonds. Hence, this ensures that all the diamonds tested follow the most accurate and consistent grading methods possible.


As one of the most trusted labs around the world, they use not one but three experienced gemologists who carefully examine and grade the color and clarity of every diamond. They act as an objective third-party observer who precisely describes the diamond and its characteristics, so you know that you are purchasing a diamond that is genuine and real.

5 Gemological Science International Diamond Certification (GSI)

To ensure an objective, accurate assessment of your diamond, GSI takes the help of advanced tools and automation. They have labs established on four continents and have made their mark in several countries, including India, UAE, Israel, and China. Known for their integrity and transparency, they often have a similar grade, such as a GIA-certified diamond.


Their comprehensive report includes certified diamonds that are thoroughly graded and laser-inscribed with the GSI watermark. Lastly, they also map the characteristics of clarity using plotting reports.

6 Antwerp World Diamond Center (AWDC)

Antwerp World Diamond Center or informally known as AWDC plays frontrunners in the global diamond trade. Each diamond is graded independently and without bias by many gemologists at the lab. These individual grades are then compiled and analyzed to form the final grade.


Apart from evaluating the 4Cs, they also tell you about how flawless and clear your diamond is and even will evaluate its size. They also largely work towards educating and empowering the consumer about why certifications are required for lab-grown as well as naturally mined diamonds.

7 Solitaire Gemmological Laboratories Ltd. (SGL)

This international gem testing lab is known for lab-grown diamond screening. Their labs use the most cutting-edge analytical tools to authenticate diamonds. They also map its origins and possible treatments in a scientific and objective manner. Each report issued is a hallmark of integrity and accuracy, and the backbone of SGL is state-of-the-art technology and skilled professionals. Today, this British-American diamond certification lab is present in over five countries.


All the above-mentioned labs are trusted to assess lab-grown diamonds accurately around the world. And while the diamond grading process is very similar to most diamond certification labs, keep in mind that it isn’t uncommon for a diamond to get a different grade from a different lab.


However, this does not mean the results aren’t accurate because the same lab can also offer different results if sent back for a second round of grading. Having said that, to ensure that you get your hands on an authentic lab-grown diamond, ensure it comes with a certification from a globally recognized diamond certification and authentication laboratory.
