For generations, diamond appraisers and those who set prices for diamond jewelry in general, have relied on four evaluation categories in order to judge the quality of a diamond. In the industry, these are called the “Four C’s” and they are set like Mount Rushmore in the complex art of diamond quality assessment.
Below is a summary of these vital four characteristics.
How do diamond appraisers judge quality?
- Diamond “cut” – That all-important quality, diamond brilliance, derives mostly from the cut of a diamond. For example, a round, oval, pear-shaped or marquise cut diamond will usually offer more points of reflection, and therefore higher overall brilliance, than an emerald-cut or square diamond, which has far less facets. The expertise of the cut is what’s important here.
- Diamond “color” – The highest-quality diamonds exhibit the least color. This is because they let more light through the stone, making it more fiery.
- Diamond “clarity” – This category refers not only to the natural clarity of the stone itself, but also to the stone’s tiny blemishes, which detract from its intrinsic value.
- Diamond “carat”– This refers to the actual size of the diamond. Many uninitiated diamond jewelry buyers are under the misapprehension that a diamond’s size is its carat value, but the reality is that a diamond’s carat is determined by its weight. Obviously, the heavier the stone, the more pricey it will be.
Diamond Buyers NYC has added another “C” to the usual list: Certification. This is a report from a diamond-appraisal expert stating their official assessment of the diamond’s current market value. Such a certificate is only accurate when it comes from a certified gemologist. At Diamond Buyers NYC, that is the only kind of appraisal we do.
