The Colored kim cương Grading Report

The colored diamond grading report, which is recognized as a full GIA đá quí certificate, provides all the relevant kim cương details.

Colored đá quí Identification và Origin Report

As mentioned above, the GIA also offers a second report. It is called the Colored đá quí Identification và Origin Report (A.K.A "Color Only" certificate). This diamond certificate is just as valid, but offers less information. It focuses only on the color grade và the Origin of a colored diamond & lists the following data. The report is divided into the following sections:

General Information
Grading Results
Additional Grading Information
Reference Diagrams
Scale References
Bar Code, Disclaimer, và Security Features

When khổng lồ Choose The đá quí Identification and Origin Report

A full GIA certificate is always preferable. However, if the clarity level of a kim cương were low, it would be wise lớn request a half certificate, since it is far less expensive và will keep the price of the kim cương down. Full certificates include clarity grades, explanations regarding the cuts, polish, symmetry, fluorescence, and other important information. The half certificate on the other hand does not danh mục any of this information, và simply supplies the diamond’s weight, origin, color grade & distribution, measurements, và shape and cutting style.

Once you have the certificate, whether half or full, you are able to lớn verify the authenticity of the diamond through the GIA website.

Is This Standard Across all Stores?

We hope one day to come at this section, scratch all text on it & clearly say yes, but unfortunately, the number of stores (both online & physical) showcasing và selling low-quality stones is increasingly growing, many are using fake GIA certificates as well!

For this reason, nowadays, it’s becoming more important than ever to kiểm tra the GIA certificate if it’s real, official, legit, và if it actually represents the kim cương you’re thinking of purchasing!

While our favorite online vendors; that we always recommend you lớn buy your diamonds from are 100% safe on this front, nevertheless, you might still want lớn double-check the certificates with less-known (or some scammy) online đá quí vendors & in local stores.

Before going full “detective Conan” on this & discovering how to tell if the GIA certificate is original or fake, a good place to start would be to examine together how a typical GIA certificate actually looks like.

GIA Certificate Sample

Here is a sample of GIA report, it contains everything you need khổng lồ know about the kim cương (click the image for a larger view, opens in a new tab):


The certificate contains several sections, starting by the 4Cs.

Mentioning the 4Cs, we think it’s important khổng lồ see why -in order of importance- diamond Cut is the most important diamond characteristic among them.

Then we see more details about polish và symmetry, visual measurement representation, and other info as well.

GIA Report Number Lookup: Verifying the Certificate Online

Before doing any kind of inspection whatsoever, every GIA report/certificate has a chất lượng number (10-digit) on its top, this number is unique for every report issued by certificate, and chú ý here we’re saying unique per certificate/report, but not per diamond, why?

Because đá quí can be inspected more than 1 time by GIA (or any other lab), & in this case it will get a new report number.

How lớn Verify if GIA Report is For a Specific Diamond?

Faking a GIA report (as a piece of paper) is easy, but what’s easier is checking it online in less than a minute khổng lồ know it’s fake!

The thing is that it’s not only about having an official report by GIA, some “amateur” stores provide real GIA reports, but for different diamonds!


So when we check the GIA report, any report, we need khổng lồ notice what makes it real, and what makes it for the diamond we’re checking!

Look now again the sample report above, other than all đá quí specifications on the left (4Cs, measurements, Polish, Fluorescence, etc…), take a look at these:

1. QR Code:

Starting 2014, GIA started to include a QR (Quick Response) code khổng lồ ALL reports, it’s added at the bottom right of the certificate.


Scan it lớn go to the diamond Report kiểm tra Page on GIA. If the report is older than 2014, it won’t be there, but it would be a good question to know why a đá quí wasn’t sold for all that time (or maybe it’s a second hand diamond?).

Here you can verify that the link you reached shows the exact report you have (including report number).

2. The Clarity Characteristics Section:

This is the MOST important thing you need khổng lồ look at your report. If your diamond is more than one carat, the GIA report will have this in the middle-lower section.


This Clarity section will tell you where exactly the inclusions appear on the diamond (unless it’s flawless which is a very rare grade, và we believe it’s impossible for someone to lớn have one and willing to lớn use a fake GIA to sell it).


If you’re on a website that doesn’t show a magnified image of the diamond, DON’T shop there. Never get a diamond without seeing it.

That’s why we always recommend getting from the known brands like James Allen, Blue NileWhiteflash, which provide all the details necessary about the diamond.

For example, if you look at this diamond on xanh Nile, and then check its GIA certificate clarity section:


You will be able lớn match most of inclusions you see on the diamond, this is more easily doable on James Allen with their insane 40x magnified 360 HD videos (even with 20x since their imaging công nghệ is superb).

If you’re in a local store, ask lớn see the đá quí under magnification, every store will have a magnifier (loupe) lượt thích this one:


Look at the kim cương on the exact locations pointed in the clarity section and match inclusions between report & the diamond in your hand.

Inclusions on the report are 100% accurate, & if you saw an inclusion that’s not on the exact location marked on the report, it might be a fake one, & you better get out of that store.

If you’re more into diamonds & can tell what type of inclusion is it, you can also match the location with the type as well, such low-quality stores will try to match diamonds with the same inclusion spots, but it’s less likely lớn match inclusion types as well!

3. Other Considerations:

You may want to check & match ALL characteristics of the kim cương on the certificate with the ones provided, it’s less likely a seller will have unmatched characteristics, but you never know, as Einstein once said

“Two things are infinite: the universe and human stupidity” Albert Einstein

If you’re good in numbers và giving approximations, try to lớn see if the dimensions provided for the diamond in the report make sense và match what you’ve in your hand.

Look at the Hologram, security code, QR, all information on the GIA report, something there will tell you about that.

4. Save Yourself All This Hustle & Buy From Trusted Stores

We really believe that this is too much work to lớn do! You already have your plate full with things khổng lồ prepare for getting the diamond, whether it was for an engagement proposal, or just a regular purchase.

You better spend your time on learning more about how to find the best diamond at the best price, not how to lớn be “scammed” by such kim cương retailers, actually, why you might be shopping from a place that you already have worries about?

That’s why we always recommend shopping diamonds online from reputable stores, & here are our vị trí cao nhất 3 vendors:
