Like the EGL, this for-profit diamond certification lab is prominent throughout Europe, but is also popular in the United States. The biggest problem with the IGI is their laxed diamond grading standards. While all diamond certification entities range in their accuracy and grading systems — the most accurate is the GIA.
Their ability to maintain independence from jewelers and their commitment to operate as a non-profit, educational organization is important.
Good, accurate certifications help customers know that the diamond that they are purchasing is exactly what the jeweler says it is. Are you interested in creating your engagement ring with a loose diamond from our inventory? Contact Sergio jfjco. Want to see some examples of our work? Take a look at our engagement ring photo gallery and video gallery. Keep in mind that you are buying a diamond, not a piece of paper.
This lab report or certificate will be issued by a grading entity and describes various elements of the diamond, such as Color , Clarity , length and width. Trained professionals evaluate, scrutinize and measure the diamonds using professional tools, such as a loupe or microscope. Each entity grades and describes diamonds differently—and sometimes the difference is significant.
Because diamond certificates are not created equal, the price and value of diamonds are not comparable across varying certifications. Ensure that you purchase a diamond with a certificate from a highly reputable grading entity—and that you review the diamond closely before purchase. Can you tell which is which? To highlight the importance of this issue, take Color grades as an example.
We recommend sticking with an H color or better when putting a diamond in a setting like this one from James Allen. You may think you have found a steal with an H color diamond with an IGI certificate. But once you have it home, you realize the diamond has a yellow tint. Regardless of the certificate you receive, the price of the diamond should be heavily evaluated. The price should reflect the actual quality, beauty and Cut of the diamond—both on the certificate and to the naked eye.
For questions about diamond prices and certifications, contact us. Every lab has its quirks. Some are looser in grading Color, while others are looser with rating Clarity. Some labs will always upgrade specific Color ranges, while others favor particular arrangements of inclusions. Smart diamond companies use this knowledge—gained from sending thousands of diamonds to different labs each month—to maximize their results. Knowing which labs are trustworthy and consistent will help you avoid purchasing a diamond worth much less than what the certificate is stating to be true.
If you have questions about the differences between diamond certification labs, contact us. That means you can trust their grading in all aspects like Color , Clarity and Cut quality. These labs also grade more rigorously than other labs. They are incredibly consistent and provide the greatest peace of mind when purchasing any diamond. GIA has no financial stake in the sale of the diamond and evaluates diamonds on a variety of qualities and elements, including:.
GIA has a reputation for rating rated Color and Clarity, the most subjective scales, more rigorously. We have also recently developed Ringo, a patented artificial intelligence model, that can examine videos of diamonds and determine if they are eye-clean.
Now that the GIA has entered the cut grade game, though, their share in this market has dropped significantly. AGS is still the go-to choice for many retailers selling perfectly cut round diamonds.
If there is a diamond that is somewhere in between grades, a manufacturer or retailer may send the diamond to multiple laboratories looking for the better grade. Its far more likely that the grades will be the same, but its possible they will get the upgrade which more than makes up for the cost of sending it to AGS for certification.
But AGS is not as commonly used for non-round diamonds. So if a retailer has 50 cushion cut diamonds, 49 of which are GIA certified and one AGS diamond, that diamond is likely to have received an upgrade. This is not a knock on AGS, merely an observation of how some wholesalers and retailers may try to take advantage of the end consumer. All in all, AGS is a very reliable laboratory.

Hi Terry Thank you for sharing your knowledge and steering me in the right direction.
Very much appreciated. I am looking to get into buying and selling diamonds so resale value is important to me. Take a look at this thread to know more. The good thing is, IGI grading reports might have become better in the last years. Should I always avoid EGL diamonds without exception? And I cannot recall a single case in which you would do better choosing the EGL graded diamond.
