GIA Vs IGI – What’s the Difference?

IGI vs GIA are both diamond grading laboratories, but what’s the difference between the two? The GIA is the most prestigious, and its reputation precedes it. The IGI is not. Despite being more expensive, IGI’s quality and consistency are comparable to GIA’s. Generally, a better IGI grade will yield a higher price tag.

Grading standards

The GIA and IGI have very similar grading standards. Both labs graded a diamond the same, but in some cases, IGI was stricter than GIA. In these cases, the IGI was more stringent. The GIA was slightly looser in three cases and strict in five. The IGI had a higher rate of agreement in three cases. It is also possible that IGI uses different grading lamps.

In a recent study, IGI and GIA agreed on clarity grades in 10 out of 29 cases. In all but three, they were within a grade. In the remaining three cases, IGI was stricter. Similarly, the GIA was more liberal in four cases. The IGI is generally more consistent than GIA, but there is always a risk that the two laboratories might have slightly different color-grading standards.


IGI is the preferred diamond grading lab in the United States, largely due to their high level of expertise in gemology. Their staff includes more than 650 gemologists and jewelry experts. Their credibility and expertise in diamonds and jewelry has helped the IGI become a household name in the industry. In many cases, the IGI’s price tag is lower than the GIA’s.

In contrast, GIA and IGI aren’t necessarily the same. Both diamond grading laboratories have different ways of evaluating a diamond, and the IGI is generally stricter than GIA. The IGI is more lenient, while GIA is more conservative. The IGI is often more conservative, so it’s easy to make mistakes. It is a bit difficult to compare the two labs’ methods, but it’s possible to see where the differences lie.

In the majority of cases

The GIA and IGI were both in agreement on the color grade. In contrast, GIA’s reports tend to be more precise and are more popular in Asia. In recent years, however, IGI has been gaining market share and has become a leader in diamond certification. This is a key reason to trust diamonds from IGI’s grading report.

While IGI is a more precise grading lab, it doesn’t offer many options to sellers. This is why they are not a perfect match. The IGI grade is half a grade better than the GIA grade. Moreover, the GIA is more rigorous than the IGI. In a recent study, IGI was more exacting than a GIA-graded diamond. Its J color will have more tint than an IGI-graded diamond.

Color grading

While IGI vs GIA lab grown diamonds is more consistent than GIA when it comes to color grading, IGI’s cut is also more accurate than GIA’s. The GIA is more consistent, but its grading standards differ. The IGI’s reports are more reliable than the PIA’s. It’s important to note that IGI has a higher standard of color grading than GIA, so you’ll need to make sure that your diamond is properly graded.

While IGI’s clarity grade is often less precise than GIA’s, it is consistent with GIA’s. In 20/29 cases, IGI and GIA gave the same grade, while in seven cases, both were within one grade. Nevertheless, if the GIA is more accurate, it is usually a better choice. If you’re looking for the best quality diamond, look for a diamond certificate that has a higher IGI grading scale.


IGI’s diamond grading scale is more stringent than GIA’s. The GIA’s reports have higher prices and are therefore less valuable. IGI’s certifications are more trustworthy than GIA’s. In addition, IGI’s reports are also more reliable. In addition, the IGI’s certifications are more readable and reliable. It is important to understand the differences between the two grading scales.


An IGI certificate is similar to a factory’s certificate. Its grade is higher than the GIA’s. GIA is more expensive, but the IGI will charge you more for a stone. This is a fair comparison based on the clarity and cost of diamonds. A GIA grading report will cost more, but the GIGI is the better option if you’re shopping for a stone.
