Decoding the Science: How to Verify a Lab-Grown Diamond

Welcome to the dazzling world of lab grown diamonds! These stunning gems have been capturing hearts and captivating imaginations with their beauty and brilliance. But, how can you be sure that the diamond you're eyeing is indeed a lab grown diamond? In this blog post, we will delve into the process of verifying lab grown diamonds, so you can shop with confidence and know exactly what you're getting. So, let's embark on this sparkling journey together and uncover the secrets behind these mesmerizing creations!

What are lab grown diamonds?

Lab grown diamonds, also known as synthetic or cultured diamonds, are created in laboratories using advanced technology that replicates the same conditions under which natural diamonds form. These lab grown gems have the same physical and chemical properties as their counterparts mined from the earth.

Unlike natural diamonds, which take millions of years to be formed deep within the Earth's mantle, lab grown diamonds can be produced in a matter of weeks or months. They are created by exposing carbon atoms to intense heat and pressure inside specialized machines.

The result? A diamond that is chemically identical to its naturally occurring counterpart. In fact, even experienced gemologists cannot differentiate between a lab grown diamond and a mined one without specialized equipment.

One key advantage of lab grown diamonds is their ethical footprint. While mining for natural diamonds can have environmental impacts and involve human rights concerns, lab grown stones are conflict-free and environmentally sustainable.

Moreover, lab grown diamonds often offer better value for money compared to their natural counterparts. They typically cost around 75-80% less than mined diamonds while still possessing the same beauty and quality.

So whether you're looking for an engagement ring that symbolizes your love story or simply want to add some sparkle to your jewelry collection, consider exploring the world of lab grown diamonds for an ethically conscious choice that doesn't compromise on brilliance or elegance.

How to verify if a diamond is lab grown: 


With the growing popularity of lab grown diamonds, it's important to know how to verify their authenticity. Luckily, there are several methods you can use to ensure that a diamond is indeed lab grown.

One of the most reliable ways to verify a lab grown diamond is through certification. Reputable labs such as the International Gemological Institute (IGI) provide certificates for lab grown diamonds, just like they do for natural diamonds. These certificates contain detailed information about the diamond's characteristics and origin. It also specifies the 4C’s i.e. Cut, Colour, Clarity and Carat wt of the diamond.  

The certificate acts as proof of the authenticity and quality of the lab grown diamond you are considering buying. It gives you peace of mind knowing that you are getting what you paid for. The certificate also serves as important documentation if you ever decide to resell or upgrade your lab grown diamond in the future.

Laser Inscription

In addition to certification, another method of verification is laser inscription. All certified lab grown diamonds are laser inscribed with a unique identification number or logo that indicates they are man-made. This laser inscription can be easily seen under magnification and serves as an additional proof of authenticity.

This inscription is marked on the Girdle of the diamond and clearly mentioned in the certificate. 

It's worth noting that while these methods are effective in verifying if a diamond is lab grown, they may not always be foolproof. Some unscrupulous sellers may try to pass off imitation stones as lab grown diamonds by using false certifications or removing laser inscriptions.

Therefore, it's crucial to purchase from reputable jewelers who have established credibility in selling genuine lab grown diamonds. Doing your research and buying from trusted sources will help ensure that you're getting exactly what you pay for – a beautiful and authentic lab-grown diamond!

It's important to note that not all certifications are created equal. When purchasing a lab grown diamond, always look for trusted certification bodies like IGI and that have established reputations within the industry.


To ensure a diamond is lab-grown, check for certification from renowned institutes like IGI and look for laser inscriptions indicating its lab origin. If uncertain, consult a trusted jeweler or gemologist. This way, you can confidently purchase sustainable, authentic lab-grown diamonds.
