What is the most reputable diamond certification?

The GIA
The GIA (Gemological Institute of America) is the most well-respected and renowned diamond grading entity. They are incredibly consistent and provide the greatest peace of mind when purchasing any diamond.

Which is better IGI or GIA?

GIA is often held up as the gold standard of diamond grading while other labs are purported to have looser grading standards. For two diamonds of the same carat, color, and clarity grade, an IGI certified diamond is on average 12% cheaper than a GIA certified diamond.

Are lab grown diamonds GIA certified?

Yes. GIA has been grading laboratory-grown diamonds since 2007. Beginning July 1, 2019, GIA Laboratory-Grown Diamond Reports and identification reports no longer use the term “synthetic.” The GIA Laboratory-Grown Diamond Report includes the standard GIA color, clarity and cut grading scales for reference purposes.

What if my diamond is not GIA certified?

Without a certificate, you can never be certain what you are buying. If a diamond is not certified, your only source of information about its quality is the seller, and needless to say, the merchant’s assessment is not likely to be the most objective.

Are IGI reports legit?

While IGI is a reliable lab, it is still not as strong as GIA. Moreover, buying an IGI diamond with lab reports from their more established labs in the U.S. and Europe might be a good ideal. It is also important to note that IGI is not as inconsistent in low grade diamonds as they are in high grade diamonds.
