Among the "four C" standards for diamond valuation is color. Just like all the other rating categories, a diamond with a superior color grade will always carry a higher price than a diamond with an inferior grade.

When shopping for diamonds, you'll likely come across diamonds that fall into a wide variety of color grades, though little differences can sometimes be quite difficult to discern. Colors are just as important as some of the other 4Cs, so it's a fantastic idea to be aware of what the different colors rating mean.

You may have heard of the term "fire of a diamond" but are yet to understand what it entails. Diamonds split light just as prisms do. The resultant spectrum displays colorful flashes, and these flashes are what are referred to as the flame of that diamond. The most fire stems in the most colorless diamond rock. Such a rock has a very substantial grade according to the diamond colors chart and thus you should expect to fork out a fortune for that stone. Further on, the color chart gives various descriptions to help one understand the different grades of colorlessness of a diamond.

Mаnу реорlе fоllоw thе dіаmоnd соlоrs сhаrt frоm thе GІА - Gеmоlоgісаl Іnstіtutе оf Аmеrіса оr thе АGЅ - Аmеrісаn Gеm Ѕосіety. Both graphs grade diamonds from the colorless to the yellowish or brownish ones. The AGS's scale is graduated from 0 to 10 (colorless to elaborate yellow) while the GIA's is D to Z (colorless to light yellow).

A factor known as fluorescence can also influence the color of a diamond, i.e., the effects of exposure to ultraviolet rays. Being present in the sun's rays, ultraviolet light affects diamonds both positively and negatively. It provides an unsightly milky white color to colorless stones (thus lowering their value) and gives a whiter bright shade to lower color diamonds (thus adding value). Ultraviolet light effects may also be unnoticeable in some diamonds.

However high or low a stone is on the diamond colors chart, the diamond's setting has a major influence on the color. The common suggestion thus is that for yellow diamonds white gold or platinum setting is advised, while colorless diamonds shouldn't have yellow settings as they wіll gіvе thе stоnе а уеllоw shаdе. The setting you to prefer will affect the stone's final color and so contemplate the other C's will help you end up with just the correct color. In choosing fancy colored diamonds, the rarity of the color, richness of the color, and purity of the color, are the aspects used to find out the colored diamond's vаluе.

Which color tier represents the best value?

The diamonds that we most commonly see in jewelry shops and especially as rings on the left hands of married or engaged women are what seem to be clear or colorless. While thinner diamonds tend to be somewhat more mined around the world, there does, in fact, exist a wide variety of colors.

J-L-rated may also be a fantastic value for buyers on a budget, as the yellow tint in these diamonds is still only slightly noticeable, and doesn't have much of a negative effect on the diamond's overall appearance.

Colored diamonds aren't fake, and they are not gemstones. They are real - structurally and atomically identical to the more commonly seen and worn colorless ones. These  colored gems, sometimes known as, ‘fancy colored diamonds,' have the very same qualities, as far as extreme hardness and hardness, like those of the conventional white diamonds.

The color of diamonds is determined by the planet's natural chemical interactions. All diamonds are formed within the earth. Colorless diamonds are formed from carbon dioxide but in more rare instances, other minerals, not usually present, come into contact with the carbon during the creation of the stone, which is what creates a variety of diamond colors. Different minerals impacting the carbon during its transformation into a diamond will produce unique colors. For example, rare blue diamonds such as the famous Hope Diamond are the result of the added mineral boron through the formation process.

When selling your diamond to a purchaser, color is always taken into account when determining its quality and value. More rare, brightly colored stones are worth a premium as are the gems in the opposite end of the color spectrum; the purely transparent, colorless diamonds. White diamonds are assessed using colorless diamonds as an industry standard and categorized on the GIA diamond grading system, entirely separate from how genuine fancy colored diamonds have been evаluаtеd.
