Why IGI Grades Diamonds More Strictly

In this article, we compare igi vs gia diamond. We also compare their clarity and color standards. The results show that the IGI’s grading standards are on par with the GIA’s. This article will examine whether or not IGI grades diamonds more strictly.

IGI grading standards are at par with GIA

While IGI diamond grading standards are close to the GIA’s, they are not identical. In some cases, IGI diamonds can be of better value. However, GIA diamond grading standards are higher than those of the IGI.

The GIA’s grading standards are much more stringent than those of the IGI. They tend to be the strictest when assessing color. HRD and AGS closely follow GIA’s color grading standards, while EGL USA generally gives one to two grades higher. For instance, an F color stone graded by the GIA would get an E grade from IGI, but a D from EGL. However, this could be due to IGI’s smaller sample size or differences between the grading sites.

If you’re looking for diamond grading standards that are close to GIA’s, you should visit the International Gemological Institute in New York, NY. The IGI’s grading standards are similar to GIA’s, but its certification standards are higher. The IGI’s certification isn’t as prestigious, however, and diamond professionals hold IGI’s grading standards in lower regard.

Despite the differences in the quality of diamonds, GIA is the first choice for many diamond buyers. The IGI’s diamond dossiers, however, are less detailed than GIA’s. IGI’s reports can be confusing and may not give you the information you need to make an informed decision.

IGI and GIA are consistent on clarity

gia vs igi grade diamonds differently, but they are consistent on clarity. During clarity assessment, a diamond’s size, color, and nature of internal inclusions are evaluated. The GIA scale ranges from FL to I2, and the IGI’s scale runs from 0-10.

GIA’s certification is more expensive than IGI’s. It is a better choice for those looking for a diamond with the best clarity. GIA reports are usually more accurate than those from other labs, but you may want to consider the IGI report for your purchase.

Both GIA and IGI assign the same clarity grade, but IGI is slightly looser in their grading process. In a recent study of 29 diamonds graded by the two laboratories, the two organizations were within one clarity grade of each other in all but one. As a result, IGI diamonds tend to be cheaper than GIA diamonds.

While IGI’s diamond certification is cheaper than GIA’s, it does have its downsides. Its turnaround time is fast, but results are inconsistent. As a result, you may be left with a weaker investment. It is better to wait for a diamond certified by GIA. But keep in mind, if you’re going to spend money on a diamond, you’ll want to find a lab that is consistent with GIA standards.

IGI also offers certificates that are comparable to GIA’s. This is useful for those who want to compare different diamonds. They can also be useful for those who want to buy diamonds at a discount. If you’re looking for a diamond to buy, IGI and GIA are both trustworthy.

IGI and GIA are consistent on color

The IGI and GIA are generally consistent on color, but there are some differences between their assessments. IGI has more stringent standards, while GIA is a little less stringent. The two organizations do not always grade diamonds the same. They sometimes use different grading techniques to determine the grade of a diamond, and this could lead to discrepancies in the grade. However, both laboratories are usually within a few percent of one another.

The GIA is an internationally respected authority on diamonds, colored stones, and pearls. Their standards and knowledge are recognized in every continent. Because of their reputation, diamonds certified by the GIA will usually be higher in price. The GIA was also the first institute to develop the 4 C’s system for diamonds and colored stones, and these standards remain the gold standard today.

While IGI and GIA are consistent on the general color of diamonds, there are some important differences between them. IGI is more widely recognized in the industry, but its certification may not be as exact as that of GIA. The IGI also has a more extensive range of services, and offers gradings for a greater range of gemstones and jewelry.


If you are considering purchasing a diamond and are looking for a diamond lab that is consistent, it’s important to consider the IGI certification. Although it can be tempting to purchase a diamond certified by IGI, you should keep in mind that you may be paying an excessive amount. The IGI labs are not as stringent as GIA or AGS, which means that you’re not guaranteed a high-quality stone.
