The 4 C's of Diamonds

Cut

When people think of cut, they often think it’s the shape of the diamond. But, it’s about how light is returned due to a diamond’s facets. Cut is responsible for brilliance, fire, and scintillation of a diamond.

Brilliance = combination of all of the white light reflected internally and externally

Fire = a scattering of light into a play of color

Scintillation = a diamond’s sparkle
For the best results, proportions of its facets, symmetry, the relationship of its weight to its diameter, girdle thickness, and quality of its polish have to come together in just the right way.

A diamond’s color is measured using the GIA® D-to-Z diamond color grading system. This system is the most widely accepted for grading. All diamonds are evaluated based on the absence of color.

No hue = higher value

This lack of color is measured in degrees based on comparisons with masterstones, made while viewing under controlled lighting and conditions. This means that regardless of where in the world the diamond is graded it will be under the same conditions and should receive the same grade. These color distinctions are invisible to the untrained eye and should be left to a trained diamond grader.

Just as a diamond’s color is graded on the absence of color, the diamond’s clarity is graded on the absence of inclusions and blemishes.

Internal characteristics = Inclusions

External characteristics = blemishes

Most are smaller than can be seen by the naked eye. And, accurate assessment is of utmost importance. So, trained diamond graders evaluate the quantity, size, relief, nature, position of these characteristics, and how they affect the appearance of the diamond.

In addition to color, cut, and clarity, carat weight directly correlates to price of the diamond. This happens because the supply is low (larger = rarer) and demand is high (larger = more popular).

1 Carat = 200 milligrams

1 Point = 0.01 carat = 1/100 of a carat

​Diamonds of equal weight are not necessarily the same size. Different proportions and depths will result in different size and weight combinations.
