Color

It would be strange to talk about color of diamonds for someone, for others it is the only thing to consider to buy unique gems. 

It must be clear the difference of meaning that exists between “the measure of the absence of color” for colorless diamonds (wrongly called “white”) and colored diamonds in one of the colors of the spectrum of visible light (yellow, orange, red, pink, blue, etc …), because the diamond is of course always colored (at least 90% are yellow, brown and gray) and only rare examples are colorless and used in jewelry. In the first sense of the meaning of “color” we are referring to one of the 4Cs (Color), which is classified according to the criteria established by the GIA – Gemological Institute of America with the assignment of a grade on the scale that goes from the letters “D” (the absolute colorless) to “Z” (deep yellow).

The color of a diamond affects a lot on her beauty, but a cut (CUT) “excellent” can get the feeling of greater color quality. The degree of color is assigned by comparing the diamond to be classified face down with other diamonds reference, called Master stones, so it is clear that this is a procedure not only possible with a diamond mounted on a jewel. From several years are available “colorimeters” electronic, analyzing the behavior of light inside the diamond, allowing the rapid and effective measurement of the absence of color.

One factor, rarely considered by buyers and not expert sellers, is fluorescence – the power to emit a secondary color visible to our eyes only with ultraviolet light. This factor (which is classified by the degree “absent” at grade “very strong”) is not absolute positive or negative, but an expert should evaluate in each case the incidence of this secondary color on the basic color, with its influence on the value of the diamond. 

Speaking about natural colored diamonds, all is different. In very rare cases, the diamonds have a color such as yellow, orange, blue, pink, etc…all natural colors due to undetectable contamination with other minerals in the 99,95 carbon chemical composition occurred during the growth of diamonds. To classify these particular diamonds a scale is used with linear degrees from D to Z, but the GIA – Gemological Institute of America, inspired from the Atlas of Munsell, has developed the parameters of Hue, Saturation and Tone, where “tint “is the basic color of the diamond,” saturation” is the strength of color and “tone” is the brightness.
