The 4C's of Diamond Jewelry

When people ask which of the 4C's – color, clarity, cut, carat weight – gives a diamond its value, the answer is, a combination of these four factors determines the diamond's value. 
Radiant Gems sales professionals are trained in helping you understand the 4C's of diamond jewelry. Their guidance will enable you to look at the diamond and see how the 4C's affect its appearance.

Color

Colors D, E, F

The D-E-F colors are known as the colorless grades. Grade "D" is reserved for larger diamonds whose colors can be more accurately graded due to their size. Diamonds less than .50 carats usually receive a top grade of "F" due to the greater difficulty of precisely grading a small diamond.

Colors G, H, I

These are known as the "face white" or "face up colorless" grades because they appear colorless when viewed through the "face up" position or through the table, but show a slight tint of color when turned upside down for proper grading. This is due to the brilliance of the stone masking this very slight tint when viewed through the table.

Colors J, K, L

This grading range offers some nice diamonds if they are proportioned properly. A well cut diamond of the K-L color range will still appear mostly colorless and can save you a good deal of money over a color grade of a higher range. Again, the cut is the key to keeping the stones of slight tint beautiful.

Colors M to Z

The lower colors "M" through "Z" have an increasing amount of yellow tint, ranging through the off colors and ending at the end of the scale, beyond which diamonds are considered to have a fancy yellow color. Be wary of jewelers offering fancy yellow colored diamonds, however. Sometimes they grade off color yellows as fancies without a proper gemological evaluation by a recognized gemological laboratory. The term fancy beside any diamond color imparts a higher value and higher price to the stone. Do not accept the term fancy for any diamond you purchase unless it is accompanied by an origin of color report and a diamond grading report from a recognized gemological lab that identifies the stone as being of natural color origin and truly fancy in color.
