GIA and IGI have different criteria when it comes to grading diamonds. The most prominent labs in the industry use precise techniques to evaluate lab diamonds. The criteria differs in each country and can be different for different types of diamonds.

For natural diamonds, GIA has stricter grading standards than IGI. However, IGI has made a name for itself as the best lab for lab-grown diamonds. The organization has been around since 1975 and is located in Antwerp, a key area in the diamond business. It has branches in many countries. It is one of the oldest gemological institutes in the world and is considered the standard for grading diamonds.

The International Gemological Institute is a vast organization that has schools and branches all over the world. It is also the world’s largest gem lab. The institute offers certifications for natural diamonds, lab-grown diamonds, and ethically grown diamonds. The institute’s grading reports are used worldwide, including Asia and Europe. GIA provides extensive reports on natural diamonds and has become the industry standard. It also offers digital diamond reports via mobile app. However, IGI reports are less comprehensive than those produced by GIA.

Both GIA and IGI have been challenging each other’s certifications, as they lack consistency in their grading methods. The latter has been challenged by jewelry owners and experts, who noted slight inconsistencies in their reports. This has led some jewelry retailers to advise their clients to avoid sending their diamonds to GIA for grading.

Although IGI grading reports are widely used in Europe and Asia, they are not as rigorous as GIA. They offer reports with variations, as well as those for fancy colored diamonds. However, the most consistent and accurate grading method is offered by GIA.

The most obvious difference between IGI and GIA is that IGI has a one point deficiency in its results. This is because IGI offers specific grading for certain qualities. For example, GIA may give the diamond a VS1 grade, while IGI may give it a VVS2 grade. This does not mean that the diamond is not of good quality, but it does mean that there is a difference of one point between the two reports.

Another difference between IGI vs GIA lab grown diamond is the price of their certificates. While the price of certificates is not directly related to the quality of the diamond, the price is often lower for IGI certified lab-grown diamonds. This makes them cheaper than GIA certified diamonds for the same diamond grade. The price of IGI certificates is 12% lower than GIA certificates.

Although both GIA and IGI have been established for a long time, it has been reported that there are slight inconsistencies in the grading of diamonds. However, the labs are making a concerted effort to improve the standards of their grading methods.

It is important to know what diamonds are certified as they can distinguish between a good diamond and a bad one. The grading report can also be used as a tool to determine the value of a diamond, since it can indicate the quality of the diamond.
