The issue of diamond certification should be considered important by anyone who buys or sells diamonds. If you’ve ever browsed through diamonds at online vendors like Blue Nile or Mondera, you’ve probably noticed that, for each diamond you select, you can view a certificate with various kinds of information.
Although this information can be confusing for people who don’t have a lot of experience buying diamonds, it is very important and can tell you a lot of what you need to know about the diamond in question. By learning a bit about diamond certification, you can equip yourself to make the most informed decision possible when making a purchase.
What is diamond certification?
Diamond certification is the result of the process by which diamonds are assessed by gemologists. Although some diamond certificates can offer slightly different information from others, in almost all cases, a diamond certificate will include detailed measurements of the diamond’s dimensions, an assessment of the symmetry and quality of polish of the diamond, and an analysis of the diamond’s quality resulting in standardized grades in the “four C” categories: cut, clarity, color, and carat weight.

The four Cs are perhaps the most important information you’ll find on a diamond certificate. These are the attributes that define a loose diamond’s value. Simply put, diamonds with high ratings in these categories will command high prices, while diamonds with low grades will be considered less valuable.
Who is involved in diamond certification?
There are several organizations involved in diamond certification. In all likelihood, the names you’ll come across most often are the AGS (American Gem Society, sometimes referred to as AGSL or American Gem Society Laboratories) and the GIA (Gemological Institute of America).
These are independent organizations who employ trained gemologists for the specific purpose of performing accurate diamond certification. They are not affiliated with any vendor, so there’s no need to worry about the certificate being skewed. If you come across certificates provided by other organizations, it’s a good idea to look into the background of the organization in question and ensure that they are independent and impartial.
Why should I care about diamond certification?
When buying loose diamonds, the diamond certificate is the most important document you’ll come across. Just as you wouldn’t want to buy a diamond without looking at it first, you wouldn’t want to make a purchase without going over the certificate. The information displayed on the certificate, in particular the cut, clarity, and color grades as well as the carat weight of the diamond, is directly tied to the diamond’s market value.
By learning more about what the individual grades mean and how they’re assessed, you can learn to determine for yourself whether the price being quoted by a diamond retailer is really in line with the diamond’s value. This, in turn, is what will give you the ability to get the best possible value when purchasing diamonds. Without diamond certification, diamond buyers would essentially be in the dark and completely unable to make informed decisions.
