We are all aware that diamonds are women's best friends, and the craze for diamonds among ladies is on another level. But do you know that diamonds come in various colors and some of these are so rare that they are found with great difficulty and concentrated only in some places? To take an example, pink diamonds are found only in one mine in Australia, and due to their rare availability, these are the most expensive diamonds that are there.
Let us look at the colors of diamonds available and study each of these in some detail to know them better.
Before proceeding further, we should know that there are colorless diamonds, diamonds with a light tone, and brilliant colored diamonds.
Where does the color come from?
There are two types of diamonds: Naturally occurring diamonds, and the other is man-made diamonds. The naturally occurring ones obtain the color from the reaction between the trace elements that get trapped in the process of formation with the carbon atoms. The presence of chemical components such as nitrogen, sulfur, and boron can color diamonds in yellow, green, and blue shades.
The man-made diamonds are created in labs and get their color from the chemicals mixed in their formation. Human-made diamonds can be of any color, but these are not as expensive as the real naturally occurring diamonds.
Color Scale for Colorless Diamonds
The industry standard for grading diamonds, widely accepted, is the Gemological Institute of America (GIA) scale. The GIA has standardized diamond color grading on a D to Z scale.
Similarly to the International Gemological Institute (IGI), who also uses a similar D to Z scale but for lab-grown diamonds. All diamonds on this letter scale are considered "white," although, on the lower end, they can have a tinge of yellow.
Grading for Colored Diamonds
Like the process for grading colorless diamonds, a diamond's fancy or intense color is graded similarly by comparing it to master stones of a predetermined color. Unlike diamonds that are colorless, fancy colored diamonds are graded face-up.
An essential factor in determining the value of a naturally-colored diamond is the intensity of its color. The cost of an intensely colored diamond increases with the strength of the most prominent hue within the stone.
Value of Colored Diamonds
Colored diamonds are much more expensive than those colorless or transparent white diamonds that we often see in the engagement rings. These are still easily available, but the colorless diamonds are difficult to spot and procure as these take many years to form, and the best ones are found once in many decades.
There are several colors of diamonds that we have seen in this article, with each having its value and aura. These are most sought, and miners often look for them because these are rare, and people value them immensely.
