Different Laser Codes On The Diamond’s Girdle

When diamond jewelers try to distinguish between lab-grown diamonds and natural diamonds, one of the first clues they can look for is the diamond’s laser inscription which acts as its identity card, and it can be found on the Girdle of the diamond.

To protect customers and provide them with transparent information about the diamond that they are buying, the lab grown diamonds are marked with 'LABGROWN' on their girdle next to the unique diamond identification number, which can only be seen clearly under magnification and does not affect the diamond’s appearance. Thus, their can be a clear way to differentiate between lab grown diamonds and natural diamonds while also protecting the value of the natural diamond industry.

As a professional diamond sellers, we at RAGAZZA all our diamonds both lab grown diamond and natural diamonds have laser inscription codes on the diamond girdle and our customers are provided with an international certification from GIA or IGI that matches the diamond that they buy in order to protect them and their investment.

Flaws When Creating a Lab Grown Diamond 

Another difference noticeable difference under the magnifier between lab grown diamonds and natural diamonds is the difference between their inclusions. The formation of both lab-grown diamonds and natural diamonds involves a certain degree of randomness. Therefore, most diamonds, contain impurities except for those very few diamonds which could be graded flawless,.

When comparing the flaws and inclusions of natural diamond with those of a lab-grown diamond you will notice that the inclusions in a lab grown diamond would look neater. For example, there would be perfectly round spots, tidy cracks, and evenly dispersed impurities. That is why, if you are looking for a diamond with a relatively low clarity (below SI1, for example), you could check if the inclusions are too neat, or have the diamond examined by our diamond professionals.

As for diamonds with clarity of or above VS1, since it only contains some trivial flaws, its appearance would be barely affected, regardless of whether it is a lab-grown or natural.

Unnatural blue tone Color in Lab Grown Diamonds

Lab grown diamonds created through the HPHT (High Pressure High Temperature) method may contain a slight blue color tone (also called blue tinge) because of the chemical boron that is used during production of lab grown diamonds. On the other hand, natural diamonds would usually contain a yellow tone because nitrogen is present during the formation of natural diamonds deep within the earth's mantle.


The blue tone of lab grown diamonds can be spotted with the naked eye; and since it is rare for natural diamonds to contain a blue color tone, this characteristic can be used to differentiate between natural and lab grown diamonds.

However, some customers prefer this blue color tone as it looks lighter than the yellow tone and the cold color hue seems to enhance the uniqueness of the diamond for them.

One thing to note though, is that the said blue tone only appears in a small amount of HPHT lab grown diamonds. As an example, if a diamond of color grade G or below has a blue color tone, the diamond certificate of this diamond would have a comment that mentions that that diamond has a “Blue nuance” or “Faint Blue”; but for diamonds of color grade F or above, no such indication would be shown on the certificate even if the blue color tone is present.

That is why we advise people who wish to buy lab grown diamonds and want to avoid diamonds with blue color tone, would be to avoid HPHT lab grown diamonds that are graded E to F on the color graded range (D color is completely colorless, so no blue tone could be seen), or to consult our diamond professionals before purchase.

Also, it depends on the quality, shine, and weight of the metal used to mount the diamond… All these factors could greatly affect whether the beauty and charm of a lab-grown diamond are properly shown.

In order to increase the value of natural diamonds, some foreign diamond brands would use metal of inferior quality for lab-grown diamond mount (such as pure silver plated with gold), or they may use complement lab-grown diamond with low-quality side stones. However, poor-quality metal could oxidize and turn dark as time passes, and this would lessen the overall beauty of the diamond.
