The Ultimate Guide to Diamond Certifications


If you are about to buy a piece of diamond jewelry, it’s a good idea you have come to this article. Checking up on the certifications that come with a diamond is essential for many reasons. Some of the main reasons you will want to check certificates at all cost is that it verifies the value of the diamond and its grading.

You shouldn’t feel hesitant when you see the paperwork, instead it goes along with the diamond to help you make a safer and smarter purchase. When searching diamonds for sale, you will want to weigh up certain things and characteristics. However, it definitely helps to know and understand more about the diamond certification.

Diamond Certification: A Guide 

A diamond certification is also known as a document which you receive when purchasing diamonds such as a pink diamond for sale. It comes from a third-party lab. Some of the most common laboratories you may have heard of are GIA, EGL, GSI and HRD. These labs create the document to clarify the stone’s characteristics that are hard for the naked eye to see. Some of these qualities are: clarity, colour, carat, length and width of the diamond. Due to the professional tools and microscopic equipment they use, they are able to reliably inform sellers of these grades so the diamond can be accurately priced.

It’s also important to note that, as several labs are out there, it’s crucial to choose the good from the bad and go with the most reputable options. All certificates are not created equal and if you see any red flags, it’s best to ask exactly what is on your mind.

Is it consistent?


With grading labs, it’s important to watch out for the consistency of grading strictness wise. For instance, GIA won’t grade a stone in the same way that EGL will for instance. Moreover, a big part of the puzzle is the lab’s reputation and knowing it is coming from a trusted source. We also recommend sticking to the H colour as it is generally most consistent. So rather than comparing grades with different certifications, look for the same gemological lab’s grading decisions and see if they are consistent and that’s your best goal 

Why is this so important? Well, there is no central body that regulates and defines what clarity and colour grades officially look like which means it’s largely subjective. So, the best way to measure the authenticity of a certificate is within its own body and comparing the other certificates the lab has produced. 

Despite the certificate and what it says, the price of the stone should be strictly and thoroughly evaluated. This is essential to having confidence in what you are buying and that it is worth the price you are paying for. It should be reflected in what you look at with your own eyes and also what the certificate backs up.
