Information to Look for in Diamond Certificates

Where diamonds come, certificates follow, and rightly so. Every diamond purchase, be it rings, pendants, or earrings, should and must come with a diamond grading certificate. Think of these certificates like the BIS Hallmark for diamonds, rather than for gold.

But why do you need these certificates to accompany your diamond jewellery? As a consumer, all you require is genuine products and assurance that the jewellery items you’re buying are real. Diamond grading certificates bring that assurance to you. They carry necessary information about diamond characteristics, anatomy, source of origin of these precious stones, and more for the buyer to understand about the diamond rock they are purchasing.

However, many shoppers are still in the dark about the information they must be looking for in diamond grading certificates. In this guide, we’ll help you discover just that. Although several agencies grade diamonds and provide different data in their reports, we’ll cover the basic information that must be present in various certificates.

What Are Diamond Certificates?

As mentioned briefly, a diamond certificate is a statement of proof that the diamond bangle that you just bought is made of real diamond rocks. The certificate carries various information, such as the type of stone (natural of lab-created), 4Cs of diamonds (cut, colour, clarity, and carat), rock measurements, and report number along with other additional details. Moreover, loose diamonds are certified as well to specify their information, which is same for diamonds that are studded in jewellery.

Usually, popular agencies like GIA, SGL, AGS, and DGLA certify diamonds that enter the consumer market. Due to their different speciality is certifying consumer diamonds, these agencies provide information in their reports that differ from one another. However, the basic details about diamond rocks are still present in all the certificates provided by these reputable agencies. At Melorra, we sell all the diamond jewellery and solitaire jewellery with stones that are certified by SGL and IGI labs, which are India’s leading diamond certification agencies. All these certificates are delivered to you along with the diamond product you order.

Different Types of Diamond Certificates

We have already mentioned that there are several diamond grading agencies, internationally and nationally, that bear the proof of your jewellery being original and real. Among the many agencies that are grading these precious stones, some are popular and hold a high position in the jewellery market.

·         GIA: The Gemological Institute of America

·         SGL: Solitaire Gem Labs

·         DGLA: Diamond and Gem Laboratories of America

·         IGI: International Gemological Institute

·         AGS: American Gemological Society

·         EGL: The European Gemological Laboratory Organization

Besides the ones listed here, there are many gemological societies and agencies, either for-profit or for non-profit, that are working on grading diamond stones. Remember that you don’t need all of these certificates with the diamonds you buy. One diamond grading certificate issued by any of these agencies is sufficient to prove that your purchase is real. Additionally, try to go for region-specific or general internal certificates when buying diamonds.

What to Look for in a Diamond Certificate?

·         Report Heading

What do you do when you meet a new person? Ask their name, of course! Similarly, when you receive a diamond grading certificate, you must always see the name of the issuing agency. It can be either one among many listed in this guide, or other certifying society that is not mentioned here.

In case the issuing agency is someone you have never heard of, do research and gather as much as information about them as possible. Several independent agencies claim to grade diamonds and sell cheap rocks to consumers. That is why being smart and understanding about different diamond grading certificates and agencies is essential.

·         Report Number, Diamond Cut Style, and Measurements

Subsequently, you need to take your attention to the report number. Just like every currency note has a unique number, every diamond grading certificate is issued with a distinct set of numbers. This number is generally used for keeping records about the diamonds and the reports. Mainly, the report number allows you to conduct a direct verification of the document via the issuing gemological agencies’ website.

Additionally, you are likely to notice the diamond cut and measurements (L*B*H) mentioned in the report to specify the diamond type that you bought. The cut gives out the information about the diamond shape (round, oval, and more), and the measurement specifies the rock’s physical dimensions, usually in millimetres.

·         Diamond 4Cs (characteristics)

Now comes the most critical information: the 4Cs of diamonds. If you know anything about diamond jewellery, you would know that every diamond is graded in four sections: Cut, Clarity, Colour, and Carat. These four categories define a diamond rock.

A diamond grading certificate specifies these four characteristics of a diamond stone. For instance, a diamond certificate might give the below-mentioned grades for these four characteristics:

Cut Grade: Excellent

Colour Grade: I

Clarity Grade: VVS2

Carat: 0.56 Carat

You can only understand what these numbers and alphabets mean when you get to know the different grades and scale that are used for defining these parameters.

·         Other Grading Information

Besides the basic information about the diamond rock, a diamond certificate also carries data, such as fluorescence, polish, and symmetry. They all provide information about how the diamond looks and behaves under certain conditions and environment. Additional comments are also given at the report’s footer about the presence of clouds, inclusions, and grains on the diamond surface.

In some cases, the reference number inscribed on the diamond is present in the report, along with some reference diagrams of how the diamond appears.

Overall, these are the necessary information that might be present in almost every diamond certificate report. However, there is still some information that is present in the documents and differs from one to another certificate.
