When shopping for diamonds, one of the most important things to consider is certification. GIA diamonds are the most highly-regarded and respected in the industry. But what does it mean for a diamond to be certified, and why is it so important? This blog post will explore the difference between certified and non-certified diamonds and explain why GIA certification is the best way to ensure that you are getting the highest quality diamond possible.

A certified diamond is a diamond that has been graded by a third-party professional gemologist and given a certificate of authenticity. This certificate will include all vital information about the diamond, such as carat weight, cut, color, clarity, and more. It is important to note that not all diamonds are certified. In fact, most diamonds on the market are not certified.


Many independent companies grade diamonds. However, the most respected and well-known company is the Gemological Institute of America. The GIA is a nonprofit organization setting the standards for diamond grading since 1953. They are responsible for creating the “Four Cs” of diamond grading: carat weight, cut, color, and clarity. It’s also important to note that GIA grades all gemstones, not just loose diamonds.


Owning certified diamonds has many benefits for the owner. First and foremost, it guarantees the quality of the diamond. When you purchase a certified diamond, you can be confident that you are getting a top-quality stone. The stone is certifiably the exact carat and color that is on the certificate. Without being certified, there is no guarantee of exact specifications.

Certification also adds value to the diamond. A certified GIA diamond will always be worth more than a non-certified diamond of similar quality. This is simply because certified diamonds are in higher demand, and buyers are willing to pay more for the peace of mind that comes with certification.

Finally, a graded GIA diamond comes with a certificate of authenticity that can be used as proof of ownership. This is important if you ever need to insure your diamond against loss or damage.

Building a Custom Engagement ring



Certified diamonds are more expensive to purchase upfront. However, they are a wise investment because they hold their value over time. Certified diamonds typically appreciate in value while non-certified diamonds depreciate.

So, when you are shopping for diamonds, be sure to look for those certified by the GIA. It is the best way to ensure that you get the exact stone you are looking for and will add additional value if you choose to sell your diamond.


There are several ways to certify your diamond. The most common way is to take it to a qualified jeweler and have them send it off to the GIA for certification.

Another way is to buy your diamond from a jewelry store that specializes in certified GIA diamonds. These trusted jewelers can sell diamonds that have been certified by either the GIA or another reputable organization.

Finally, you can send your diamond directly to GIA to be certified. However, this option is only available if your diamond is 0.15 carats or larger.

No matter which option you choose, ensure you receive a certificate of authenticity from the certifying organization. This document will serve as proof that your diamond is indeed certified.
