Interesting Facts about Diamond Certificates

One may think that buying diamond is easy. They just need to hop into a well-known store and choose the diamond of their choice. In reality, diamond buying is a daunting task, especially for the first time buyers. There is a number of technical information which should be well understood by you in order to ensure that you are not only buying the right kind of diamond but also that your hard earned money has been well utilized.

First of all, it is necessary to understand what a diamond certificate is and on what basis such a certificate is made. A diamond certificate is an unbiased and professional evaluation of the various attributes of a diamond. It is considered as an art and therefore it is subjective between different gemologists. A diamond certificate is inclusive of such precise details as carat, clarity, color and cut. In addition to this, a diamond certificate also contains details on the diamond’s polish, fluorescence, symmetry, measurements,  a graphical presentation of the diamond with the position of the diamond’s inclusions in it, as well as other comments (which includes any factors not shown in the report). Hence, certificates determine and stand testimony to the value of a diamond.

There is a plethora of diamond grading labs around the world, yet not all laboratories issue a diamond certificate based on the same grading process and nomenclature. Some labs are looser in color while some in clarity. Hence, a diamond report from one lab may not share the same result with a diamond report from another lab for the same diamond. 



Understanding the workings of the different Gemological Institutes

It is necessary to check a diamond certificate before you venture out to purchase a diamond. This will help you make a more informed decision. Let us first understand what makes the GIA certificates the most respected, trusted and followed diamond certificate in the world.

It is the Gemological Institute of America, (GIA) who unveiled the diamond evaluation criteria and nomenclature which are today followed by the other gemological labs too. At present their opinion is counted as the most authentic and most respected. One of the reasons, is due to the fact that GIA (along with AGS) are the only non-profit lab(s), which could translate into being more reliable. 

However, “Are you really going to walk around with the diamond certificate in your hand”? No doubt for your own personal satisfaction and peace of mind, a GIA certified diamond may be more preferable, but it is to be noted that there are many other reputable and trusted diamond labs and businesses in the world who have also received their due status over the years. Diamond grading is subjective, so be it GIA or any other gemological institutes, none can mathematically explain what a “G” color looks like or what an “SI1” clarity will be like.

It is true that the GIA follows a strict and meticulous evaluation process and they are done by at least four expert gemologists. The EGL and other gemological institutes, follow a more lenient grading standard, making the same diamond less expensive as a result. However, no lab (not even GIA) can guarantee that the diamond is extremely brilliant and is priced perfectly. You will be surprised to know that many certificates, including GIA, are off by 3 or more grades. 

Moreover, it is important to understand that a quality certificate and an appraisal do not mean the same thing. This is because a grading report does not allocate any value to the stone or determine the market value. The grading report only contains precise details on the quality and other characteristics like the 4 C’s. With the help of this information, an appraiser fixes a value to a diamond. So just because a diamond is a GIA certified many jewelers may increase the price of the stone. GIA certified diamonds are sold at a premium. Hence, buying diamonds that are certified by AGS, IGI, EGL, GSI, HRD and other laboratories is a potential way to save more money.

At the end of the day, it should be borne in mind that you are buying a diamond and not the certificate. It is up to the consumer to not only understand the difference in different lab certifications, but also to decide which certification to depend on, unless purchasing an uncertified diamond is an option. They need to make an informed decision based on the description of the diamond and know exactly what they are paying for. They should not just look at the lowest price, but rather should look at the stone by comparing it with other similar stones.
