The Importance of Diamond Certification: GIA vs. IGI vs. AGS

There is more than meets the eye when it comes to buying a diamond. The captivating beauty of a diamond is almost second to none, but the magic behind that glimmer is what counts in today's trend. And that is where diamond certification enters into it. 





A diamond certificate gives you the protection that your stone has been graded according to its significant characteristics, such as diamond cut, diamond color, diamond clarity, and diamond carat


But not all certifications are created equal. For this reason, do not hesitate to compare the most recognized grading labs like GIA, followed by IGI and finally AGS. Knowing what these certifications are, and how they differ from each other will help ensure you know which to look for. In this article we will explore why diamond certification is important, and what sets one certificate apart from another.





GIA Certification


Gemological Institute of America (GIA) is one of the best diamond grading laboratories that is well-known by its strict standards when it comes to diamond evaluations. It has set the bar for the highest standards that are globally recognized and practiced. GIA certified diamonds are put through a strict process and an impartial evaluation, ensuring the buyer knows exactly what they are getting in terms of diamond quality.



The main key to GIA is its constant state and adherence towards the grading scale. A GIA grading report tells the story of a diamond, and it will show expert research for all 4 C’s (carat weight, clarity, color & cut) as well as confirming other information like symmetry and fluorescence. Frequently we see GIA vs IGI diamonds or GIA vs AGS comparisons that emphasize the attention to detail that is placed on each evaluation by an entity with professional experience and an image of accuracy in their evaluations. This is for what reason GIA certification is more liked among respectable buyers.



IGI Certification


The International Gemological Institute (IGI) is also an essential third-party diamond grader. Although IGI certified diamonds are considered slightly less strict than GIA-graded diamonds, nevertheless they are widely accepted especially to international markets. While the differentiating factor for this internationally-recognized establishment is its reach across the globe which enables buyers located in various regions to gain access to IGI certified diamonds.

While some may not hold IGI certification in quite as high regard, it does provide a legitimate alternative for consumers who tend to value their dollars more than the pristine certification of GIA. This should be present if you have an IGI diamond grading report that provides all the necessary specifications and information on its quality and characteristics, this is already a good start to gaining confidence in your purchase!



AGS Certification


Another widely-respected grading lab is the American Gem Society (AGS) which has an excellent reputation for evaluating diamond cut quality. What is unique about AGS is that it evaluates diamonds with a numeric scale (0-10), and pays the most attention to the quality of cut. If one is in the market for a beautifully brilliant diamond, an AGS diamond certification can be of great value because it is known to place emphasis on an ideal cut.


AGS grading reports are not comprehensive compared to GIA but they are still trusted and sought after by many even though they focus mostly on evaluating the diamond cut. They are particularly in the United States. Like GIA, AGS maintains a strong reputation for impartiality and scientific rigor, making it a safe bet for buyers who are serious about quality.


If the diamond cut is your first preference, you can look up AGS-graded diamonds. AGS certified diamonds definitely offer stunning light performance which can only be present in diamonds with very good to excellent cut gradings. 



Final Thoughts


The jewelry industry places a high value on diamond certifications since they offer a diamond's individuality. They act as a guide for determining diamond authenticity and that shows the importance of diamond certification. Although the GIA, IGI, and AGS have different grading processes, they all contribute to a more efficient diamond trade market. Whether you are looking for diamonds for a wedding ring, engagement ring, diamond necklace, diamond earrings, or diamond bracelets, a certified diamond will give you peace of mind and ensure that your money is not wasted.


Your decision may be influenced by how a diamond is graded, but it always comes back to the most important factors: budget and diamond cut. It is usually important that you do your research before purchasing a diamond, and that you only buy from respected jewellers such as Excel Jewellers.
