5 Interesting Facts You Need to Know About GIA Diamond

GIA Diamond

GIA is short for Gemological Institute of America, and this organization tests diamonds and grades them accordingly. This organization has been leading the research in geology and science for many years, and diamond grading is just a part of what they do.

 They are but one of many international organizations that test, grade, or certifies diamonds, and each of them follows its criteria and procedures.

Top Facts you need to know about GIA Diamond:

Below are the important details.

01. These Diamonds Go Through Extensive Laboratory Tests

GIA is an ancient organization that has been leading the research on gemstones and diamonds. They even established their procedure to check diamonds, which is well recognized around the world. The diamonds are graded according to four C’s: cut, clarity, color, and weight in carat. Whichever of these diamonds fare well in the first 2 may be considered good diamonds.

02. GIA Diamonds are Not Certified, But Graded

It’s common for people to swirl around the term “GIA certified.” It should be noted that this term is false, as the diamonds don’t go through a certification test, but a report is generated against them after extensive laboratory testing. That report, in turn, is based on the four C’s discussed above and several other factors based on which the retailed determine the price that needs to be set.

03. These Diamonds are Generally More Expensive than Others

A GIA diamond, i.e., a diamond graded well by GIA, will generally be more expensive than other gradings and certifications in the market. That’s because everyone knows that GIA has stricter grading standards than other organizations, and any diamond graded by them will have gone through more rigorous testing, leaving less room for ambiguity. It makes these diamonds more expensive than others, generally.

04. Gangs Out There Attempt to Steal GIA Diamonds

These diamonds are transported via safe means, tested, and returned accordingly. But even so, there are black sheep out there that attempt to find ways to steal these diamonds, as they do with any other set of diamonds that are being transported to any other laboratory. Nevertheless, about all of these attempts have been unsuccessful so far, as GIA is a safe and secure institute.

05. Not All GIA Diamonds Are Worth Buying

Let’s roll back to fact #2. It was noted that these diamonds do not go through a certification test but have a report generated against them. It’s evident that a report will be generated against a bad diamond, and that report will show this diamond as a bad one.


Surely, buying a GIA diamond will put you at ease, as you know that you can trust those diamonds without worrying about anything. However, what you need to make sure of is if those diamonds are actually graded good by GIA or your seller is bluffing. For that, you may need to ask for the authentic report generated by GIA, which would come with a certified stamp.
