They are lighter on the pocket and available in custom shapes and sizes. Diamonds effortlessly add a touch of sophistication to any occasion, and lab-grown diamonds have encouraged people to invest in diamonds more than before. 


Do lab-grown diamonds possess the same qualities as natural diamonds? Can lab-grown diamonds be GIA certified? These are a few questions that first come to a buyer’s mind when they think of these diamonds. No doubt, these are valid questions and prove that you are a responsible buyer. Diamonds are not just for show; they are an investment opportunity for many. Hence, it’s important to verify diamond quality before buying. 


What is certification, and who certifies lab-grown diamonds?


As many of you might be aware, every gemstone comes with a unique certification that indicates its quality. This certification determines the price of the gemstone in the market and also inspires confidence in the buyer. One might wonder, who certifies lab-grown diamonds? 


Institutions with highly specialized equipment issue certifications after assessing the quality of gemstones. GIA, IGI, and GRS are a few of the international laboratories authorized to offer certifications. 


Here’s what you need to know about GIA certification


Gemological Institute of America (GIA) is one of the most reputable and trusted grading laboratories that certifies lab-grown and natural diamonds. 


Let’s delve deeper into the important factors taken into consideration while grading lab-grown diamonds. 


Clarity 


A lab-grown diamond’s clarity is classified into these categories: Flawless, Internally Flawless, Very Very Slightly Included, Very Slightly Included, Slightly Included, and Included. 


Inclusions mean any minerals trapped inside the diamond during formation. Diamonds with zero or very minor inclusions command the highest value in the market.


  1. Flawless diamonds have the highest clarity. They have no internal inclusions or external blemishes seen under 10× magnification. 


  1. Internally flawless means there might be minor blemishes on the surface visible under 10x magnification. 


  1. Very, very slightly included means inclusions that are extremely difficult to see under magnification. 


  1. Very Slightly Included means the diamond appears clean to the naked eye, but minor inclusions are visible under magnification.


  1. Slightly Included means inclusions are sometimes visible to the naked eye and clearly visible under magnification. The clarity of diamonds is quite low here. 


  1. Included means inclusions are easily visible under magnification and to the naked eye.


Flawless diamonds are rare and premium, whereas included diamonds have the lowest clarity. Buyers must check the clarity before buying to avoid regretting the decision later.


Color

GIA grades the diamonds based on its color grading scale, which goes like this: Colorless, Near Colorless, Faint, Very Light, and Light. 


  1. Colorless - Colorless means the absence of any tint in a diamond.


  1. Near Colorless - Near Colorless diamonds have a slight tint that cannot be seen by the naked eye. These diamonds also command high value in the market.


  1. Faint - Faint diamonds have a clear tint that’s visible to the naked eye. 


  1.  Very light to light - These diamonds have a visible yellow or brown tint, which reduces their market value significantly. 


Cut

Round cuts are most popular as they best show a diamond’s brilliance and fire. Cuts are graded on a scale of Excellent, Very Good, Good, Fair, or Poor. 


  1. Excellent - Diamonds with ‘Excellent’ cut grade have high brilliance and an even pattern of light and dark areas. 


  1. Very Good - Diamonds with this grade have high brilliance but may be dark around the edges or in the center. 


  1. Good - These diamonds are darker than others, due to which their brilliance is low.


  1. Fair - A ‘Fair’ grade is given to diamonds with very dark areas and low scintillation.


  1. Poor - This is the lowest grade given to a diamond. Diamonds in this category have very low brilliance with visible dark and uneven areas.


Carat

Carat refers to the weight of the diamond. GIA will list the exact weight of the stone in the report. This certification protects buyers from inaccurate weight claims. 


  1. One carat is equal to 200 milligrams.


  1. Larger diamonds are rarer, making higher carat weights more valuable.


  1. Carat weight and visual size are not always the same. A well-cut diamond can appear larger than a poorly cut diamond of the same carat weight. 


  1. You will notice that even a slight increase in carat weight leads to a significant increase in price.


  1. 1 carat, 2 carats, and 3 carats carry a premium due to their desirability and rarity.



Conclusion


Lab-grown diamonds are certainly GIA-certified. GIA ensures that diamonds are graded appropriately according to their unique characteristics. When buying a lab-grown diamond, buyers should always ask for a grading report (certificate) from the jeweller. This will help you understand whether you are buying the right quality.
