When it comes to buying a lab-grown diamond, one of the most important factors to consider is the grading report. Two of the most well-known and respected grading laboratories for diamonds are the International Gemological Institute (IGI) and the Gemological Institute of America (GIA). Both organizations provide accurate and reliable grading reports, but there are some differences between them that may influence your decision on which one to choose. In this blog post, we'll compare IGI vs. GIA and explore which one is better for lab-grown diamonds.
IGI vs. GIA: What's the Difference?
The IGI was founded in Antwerp, Belgium in 1975, and it has since expanded to include 18 laboratories around the world. The IGI is known for its innovative grading techniques and its ability to detect lab-grown diamonds, which can be difficult to distinguish from natural diamonds. The IGI grading report provides a detailed analysis of the diamond's 4Cs (carat weight, color, clarity, and cut) as well as its fluorescence, symmetry, and polish.
On the other hand, the GIA was founded in the United States in 1931 and is considered the world's leading authority on diamonds. The GIA is known for its rigorous standards and its research in diamond grading and gemology. The GIA grading report provides a thorough analysis of the diamond's 4Cs and includes a diagram of the diamond's inclusions and blemishes.
Which One is Better for Lab-Grown Diamonds?
Both the IGI and GIA provide accurate and reliable grading reports for lab-grown diamonds. However, there are a few differences to consider.
Firstly, the IGI is known for its ability to detect lab-grown diamonds, which is an important factor to consider when buying a lab-grown diamond. This is because some unscrupulous sellers may try to pass off lab-grown diamonds as natural diamonds, and having a grading report from an organization that can accurately detect lab-grown diamonds can give you peace of mind.
Secondly, the IGI tends to be more lenient in its grading standards compared to the GIA. This means that a lab-grown diamond that receives a certain grade from the IGI may receive a lower grade from the GIA. However, this doesn't necessarily mean that one grading standard is better than the other - it simply means that you should be aware of the differences when comparing grading reports.
Ultimately, the choice between IGI and GIA depends on your personal preferences and priorities. If you value the ability to detect lab-grown diamonds and want a detailed analysis of a diamond's cut, symmetry, and polish, the IGI may be the better option. If you prefer a more rigorous grading standard and a thorough analysis of a diamond's inclusions and blemishes, the GIA may be the better option.
When it comes to buying a lab-grown diamond, the grading report is an important factor to consider. Both the IGI and GIA are respected and reliable grading laboratories, but there are some differences to be aware of. Ultimately, the choice between IGI and GIA depends on your personal preferences and priorities. By understanding the differences between the two, you can make an informed decision and choose the grading report that best suits your needs.
