How do you know the true value of your diamond? What factors should you consider to assess its quality? The 5 Cs of a diamond will give you a better understanding of how a diamond piece is evaluated, priced, and valued.

What are the 5 Cs of a diamond?

Not all diamond pieces command the same price. Diamonds are graded based on their color, cut, clarity, and carat weight. Equally important in the assessment is the 5th c: confidence in your diamond.

The First C: Cut

The cut is probably the first factor that people should consider when buying a diamond. Many think of it as the shape of a diamond, but technically, it is not. The cut refers to the polish, symmetry, and proportions of a diamond.

Ideally, the cut should allow the diamond to reflect light so well that the gem ultimately sparkles. For this reason, excellent cut diamonds also look more radiant and beautiful to the eye.

The Second C: Color

Did you know that a diamond’s color can range from yellow or brown to colorless? The slightest difference in the shade or hue of the diamond can greatly affect its price and value.

The GIA color grading scale for diamonds is the standard for the industry, and the highest grade is given to pieces that are extremely colorless as they are also the rarest. However, fancy color diamonds like blue, red, and pink can be very expensive as well.

The Third C: Clarity

Diamond clarity refers to the absence of inclusions, flaws, and blemishes. To the naked eye, these inclusions and blemishes may not be evident. However, this does not mean that the gem is internally flawless.

Experts spend time studying and grading the internal clarity of diamond pieces. This is important because the position, type, size, and quantity of the inclusions can affect the way the light is being reflected in the gem. Needless to say, the lesser the inclusions and blemishes, the higher the value of the diamond.

The Fourth C: Carat

Carat measures the weight, not the size, of a diamond. One carat is equal to 200 milligrams. Of course, the price of the diamond increases with the carat weight. However, the cut, color, and clarity of the stone can affect its value.

Oftentimes, jewelers would express carat in terms of points. Thus, keep in mind that one carat is equivalent to 100 points.

The Fifth C: Confidence

The 5th C of a diamond does not refer to any of its physical attributes. Instead, it is about confidence in the diamond.

Confidence is knowing that you are getting your diamond from reputable jewelers or shops like Clark Pawners and Jewelers.

A diamond grading certificate can also be issued by an independent laboratory. This will serve as proof of the stone’s authenticity.
