In the context of Lab Grown Diamonds, IGI certifications are usually preferred by most of the companies.

Why IGI Certification for Lab Grown Diamonds? Otherwise, if the findings remain consistent, the assessment of both the labs is appropriate and reliable. The reason for such a difference is that diamond gradings are subjective in nature and hence it is not preferred to compare the certifications of two diamonds graded in different laboratories. For example, one lab may consider a diamond to be an I, while another laboratory might grade the same diamond as a J. However, there can be minor differences in their reports due to a different measure and conception of a grade in a specified category. All of these laboratories use similar standards of grading scales and assessment in providing diamond certificates. Lab grown diamond certifications are provided by a number of internationally approved laboratories- International Gemological Institute (IGI), Gemological Institute of America (GIA), Antwerp World Diamond Center (AWDC), Gem Certification and Assurance Lab (GCAL), American Gem Society (AGS), and Gemological Science International (GSI). Authorities that grade Lab Grown Diamonds This elaborate process is the most important part of purchasing and owning a diamond. The individual findings of single diamonds are further culminated into a report which comprises all the information regarding the diamond. Sometimes, a diamond undergoes more than one grading in order to attain the correct grade and certificate. As mentioned, a single diamond is individually tested and graded by the gemologist authenticated by the respective lab. The grading is based on the 4C’s of a diamond– Cut, Clarity, Color, and Carat. Hence, it is important that your diamonds are certified from reliable and authorized sources. Only with the help of highly specialized instruments and under controlled laboratory conditions one can assess, evaluate, grade, and certify diamonds. Gemologists thus, also take this into account while assessing the difference between lab grown and natural diamonds.Īs we can see, it is almost impossible to distinguish between a natural diamond and a Lab grown diamond with an unaided eye. The catch here is, in the case of lab grown diamonds, the trace elements do not largely influence the physical properties of the diamond. While a diamond encompasses 99.95% of carbon in its chemical form, the other 0.05% is attributed to the trace elements.īasically, trace elements are not a part of the chemical composition, but the presence of these atoms has a huge impact on the physical color and the shape of the diamond. Sometimes lab created diamonds also comprise trace elements, but it is mostly unlikely to have trace elements playing a greater role as they do in natural ones. In a similar way, the crystal growth is also observed to be an important facet in understanding the difference between a lab created diamond and an earth-mined diamond.Įarth-mined diamonds also have a peculiar feature, that is, ‘trace elements. Gemologists use this ‘lack of nitrogen’ in order to compare and establish the difference between a lab grown and a natural diamond.

For example, most of the naturally occurring diamonds possess elements of nitrogen in their chemical composition despite being completely indistinguishable to lab grown diamonds in their physical form. But how do gemologists differentiate between Lab grown and natural diamonds? How is the difference between Lab grown and Natural diamond established?Īlthough Lab Grown diamonds and Natural diamonds share the exact same physical and chemical properties, there are certain miniscule and microscopic differences between the two. However, they clearly demarcate the difference between a Lab-Grown diamond and a natural diamond in favor and for the ease of the customers. Laboratories follow the exact methodology and medium as a part of the evaluation. The authorization of Lab Grown Diamonds is similar to that of natural diamonds.
