IGI Vs GIA Lab Grown Diamonds

The battle for lab grown diamond certification has begun between igi vs gia lab grown . IGI has taken over this lucrative market and GIA is fighting back. But they will face an uphill battle to reclaim their crown. Read on to learn more about the two diamond certification standards. It might be time for GIA to reconsider its certification policies and procedures. Until then, IGI has the edge.


The most obvious difference between igi vs gia lab grown Diamonds is their grading standards. The GIA is more stringent in its grading of natural diamonds, while IGI is less strict. While both organizations offer certificates, GIA has the higher standard. You should always buy a diamond from a reliable retailer. There are other retailers that might try to hide the source of their lab grown diamonds, so make sure to shop around and make a decision based on your personal needs.

While IGI and GIA aren’t completely in agreement on clarity, they are generally within one color grade. In 20 of the 29 cases, they assigned the same clarity grade. In the other seven, they were 1 grade apart. Although the difference isn’t significant, it is possible that IGI has a slight bias in their grading system. This could be due to differences in grading lamps and sample size.


When it comes to diamonds, IGI and GIA are the two most common labs used in the industry. However, there is a significant difference between the two in terms of grading. GIA certifies diamonds, while IGI certifies gemstones. For many years, IGI reports only gave a general idea of a diamond’s quality. The reason is that these diamonds aren’t nearly as rare and consumers don’t need to know its exact properties.

In the last four years, the diamond industry has changed dramatically. The advent of the first gem quality white lab grown diamonds changed the game. The GIA was one of the first to embrace this technology, and it was able to expand their certification business. However, with the growing popularity of man-made diamonds, GIA has stopped certifying these diamonds.

IGI grading

When it comes to natural diamonds, the GIA is the gold standard for certification, but IGI is also an option for lab-grown diamonds. While an IGI certificate isn’t nearly as valuable as a GIA one, the IGI designation does help distinguish it from a poorly-graded one. The report looks like an ordinary diamond certificate, but it also includes a subheading for “lab-grown.” In addition, comments will explain the process of creation of the diamond.

When comparing the two lab-grown grading labs, it’s important to remember that lab-grown diamonds still undergo the same grading process as natural diamonds. Aside from the differences in quality and size, both lab-grown diamonds are graded by international certifiers using the four C’s. Nevertheless, the different growth processes produce different quality diamonds, and the nuances of color may be due to the type of growth method.

GIA grading method

The Gemological Institute of America, or IGI, is a leading gemological laboratory. They are headquartered in Antwerp, Belgium, and have nine labs and four research centers in thirteen countries. They are the largest independent gem lab in the world and employ over 1400 people in the jewelry industry. They offer fast turnaround times and affordable grading reports. They also conduct research on gems and provide education to the industry mytoptweets.

Compared to the GIA, IGI also offers a faster certification process. Since IGI operates like a factory, their grading reports are available in a matter of days, whereas the GIA can take a month or more. The cost of certification varies based on the carat weight and type of report. As a rule of thumb, GIA reports are more expensive than IGI certificates.

GIA grading consistency

GIA is one of the world’s largest independent gem labs, headquartered in Antwerp, Belgium. The lab is well known for its fast turnaround times and affordable grading reports. They also do a lot of research on gems and provide education to the industry.

Although GIA has been certifying lab-grown diamonds since 2007, they are not the leading lab in the industry. However, they were one of the first laboratories to certify lab-grown diamonds. However, those diamonds were not up to the standards GIA now uses. Furthermore, they were a lot cheaper than mined diamonds. As a result, mined diamond companies began clamoring seriously to blacklist lab-grown diamonds. Eventually, GIA stopped grading these diamonds.

GIA grading time

GIA and IGI are two of the most popular diamond grading laboratories in the world. Both are based in Antwerp, Belgium, and provide reports to jewelry retailers in the United States and across the world. Although the two labs generally use similar grading systems, they are different enough to have significant differences. For example, IGI grading is more subjective and less rigorous than GIA grading, which can lead to inconsistencies in diamond quality.

The difference between the two labs lies in terminology. The GIA uses a four-claw system, while AGS uses numerical values. In addition, the IGI uses the word “ideal” for the highest cut grade, while the AGS uses “excellent” or “ideal” to describe the diamond’s cut.

GIA grading consistency on clarity

The GIA is a nonprofit, industry-funded institution that grades diamonds. It’s been a long-standing practice to not treat lab-grown diamonds the same way as natural diamonds when grading reports. This is to protect the natural diamond market.


A recent study compared diamonds graded by IGI and GIA. During the study, 29 diamonds were graded by each lab. The GIA grading consistency was higher than that of IGI. For clarity, the GIA grading consistency was higher than that of IGI.
