If you didn’t know it yet, GIA is the entity that constructed a grading process for diamonds, according to the 4Cs (cut, color, clarity and carat).
GIA as an authority acts independently and simply put, if your diamond has a GIA rating, this organization has graded it.
Then it’s known as a ‘GIA diamond’.
If you want to buy smart, using GIA’s grading system is a wise reference to use.
Whether you’re shopping for engagement rings or other jewelry, let’s help you understand this aspect of the diamond business so you can make informed decisions.
GIA Diamonds: What’s it All About?
Let’s summarize what GIA does in the diamond industry:
It’s an NPO
They conduct research
Industry professionals obtain education from GIA
The quality of stones is determined according to the standards set by GIA
GIA handles the grading of diamonds, creating a list of relevant terms and following their 4C guideline, which uses scientific techniques to determine:
Color of the diamond
Its weight in carats
The hue or color of the stone
What does GIA NOT do?
It’s not a mine
It can’t appraise stones
It doesn’t trade commercially
By staying independent from these aspects of the diamond market, GIA remains objective and there’s no bias when it makes certain calls on grading.
Yes, this is important for all buyers to know, because you can ensure you get a quality diamond simply by specifically looking for GIA diamonds and discussing their reports with your jeweler.
The information helps you identify whether you’re getting proper value for the price you’re paying.
Is Any Diamond a GIA Diamond?
In the modern diamond market, not all stones have GIA reports yet, but many of them do.
These reports have become important because both those who sell and those who purchase gems want confirmation of a diamond’s worth; and GIA provides accurate, independent information about this subject.
So, does your diamond belong to the GIA diamond group?
Simply ask for the GIA report.
If it has authentic documentation, you’ll see feedback on the assessment according to the 4Cs as well as the stone’s own, unique GIA number.
The number can also be found on the girdle on some stones, though not all, and serves as a reference: you can go online and view the stone’s grading on GIA’s global database via the ‘Report Check’ platform.
That’s how you verify the stone’s grading and you can view all the details about the stone, as reported by the GIA team.
GIA Certification: An Explanation
It’s important to use the correct terms in the diamond industry, because calling a stone a ‘GIA certified diamond’ isn’t 100% accurate.
GIA doesn’t really certify gems, so using ‘GIA cert’ in diamond talk is wrong.
In truth, the NPO (None profit organization) is only involved in grading gems.
Be prepared to hear these references in the industry as a whole, but remember that it actually refers to ‘grading’, not ‘certification’.
Their documentation proves this, because it’s not called a certificate.
GIA provides a ‘report’ you can obtain in digital or printed format.
In the same way science labs provide documentation of their findings, GIA does too, after examining a stone, assessing it according to the 4Cs and then describing it based on the findings.
Can you see that none of these activities incorporate certification?
GIA doesn’t even mention ‘value’ in their reports.
Can GIA Really Stay Objective?
Have a look at GIA’s method of work and you’ll see the pains they go to to treat each gem objectively.
Specifically, through anonymity the agency prevents bias.
It all starts when a diamond arrives at GIA: it will be placed in a see through case without any details about who owns it.
Either this data is hidden from view, or it can be removed from the unit.
All that’s used to identify the stone is a barcode on a label. This is the tracking code used throughout the GIA grading process.
This unbiased process results in honest reporting with truthful feedback of the gem’s grading.
Another way objectivity is maintained is by using multiple graders and waiting for consensus among them.
First, graders will look at the cut, color, carat and clarity.
These findings will be reviewed by senior, experienced gemologists. They can then provide findings independently.
When the various individuals agree, only then will the diamond be given an official GIA grading.
Do You Need the GIA Grading for Your Diamond?
If you’re going to spend a lot of money, don’t you want to make sure you get what you pay for?
Researching a diamond’s value and grading is a dynamic way to ensure this.
Also, if you’re shopping for an engagement ring you want to make sure you’re offering a valuable stone, right?
A GIA grading can give you peace of mind about what you’re purchasing, so investing in a GIA diamond is the better option. You get all you need to know in one document:
Feedback on the 4Cs
Know if your stone underwent treatment
Learn about its fluorescence
