If you are into diamonds, you have probably heard of the names GIA or IGI before when purchasing diamonds. The Gemological Institute of America (GIA) and The International Gemological Institute (IGI) are two organizations that are often mentioned or involved in selling diamonds. While their job is grading the diamond, they are somewhat an indicator to pick one diamond over another. But how does it all work and which one should you prioritize if it comes down to GIA vs IGI?

What They Do

Both GIA and IGI are organizations whose purpose is to grade or examine a diamond by producing an in-depth report of its characteristics. While they don’t necessarily certify a diamond, their grading on a diamond makes it a more reliable buy for anybody shopping for diamonds and helps build seller and customer trust. The report of a diamond can help you assess and determine the quality of the gem before deciding to purchase it.

GIA

GIA is the most popular in terms of grading diamonds in this industry with consistent and accurate reports. They are known for grading diamonds by the 4 C’s, that is, clarity, color, cut, and carat weight. Although a non-profit organization, they have profound methods of testing diamonds, such as examining the sample without the influence of the owner to prevent biases. There are tons of GIA-graded diamonds on the market that you can choose from with the convenience of checking their quality.

IGI

IGI is another well-known organization that grades diamonds and other jewelry and gems. They may not be on the very top with GIA with some inconsistent reports, they are certainly building a good reputation as time passes. If it comes down to IGI vs GIA lab grown diamonds, IGI will certainly take the trophy as this is their specialty. They judge the lab grown diamond solely on the characteristics of the gem, without taking the labs into consideration.

Now that you have a better idea of GIA and IGI and their roles in the diamond industry, pick at your convenience! You are armed with what you need to buy your first (or next!) diamond without hesitation!
