Diamond Color
Talking about color in diamonds opens up a wide range of considerations which start from the nature of the diamond mineral and its millennial birth.
When we talk about color in diamonds we generally refer to colorless or almost colorless stones which are then the most popular among the buyers.
However, very very rarely, due to the presence of other minerals inside it can take on the most varied colors ranging from red to blue, to green, and to all the other colors of the rainbow.
The color classification systems of diamonds have always had an empirical method, basing this operation on the comparison and infallibility of the expert eye. In recent times the advent of specific scientific systems, used by the most important analysis laboratories, allows reaching unthinkable results in environments that do not release any reflex, and therefore we could define totally aseptic.
The most used of all existing systems is the one used by the Gemmological Institute of America (GIA). It has over 20 color grades, identified alphabetically by D-Z.
Considering the incidence of the color in the value of the diamonds, the most appreciated is the D color (GIA) totally lacking in any type of color shade in addition to absolute white.
In the strong colored diamonds, in the various shades of the rainbow, you enter the world of absolute rarity and the values take on unimaginable tones.
FANCY DIAMOND COLOURS
A diamond crystal is colorless. Any color found in a diamond is caused by impurities within its crystal lattice structure.
This type of impurity includes diamonds with intense colors ranging from straw yellow to intense brown. In an absolute rarity, we can classify the colors blue, pink, red, and even green.
In general, all experts agree that rigorous cutting standards cause most of the raw material to be lost, thus increasing costs. It must be taken into account that these dispersions cause price increases between the different types of cuts. The ideal or better cut makes the value of the diamond grow.
These small impurities inside the diamond are constituted by irradiations which in the magical moment of birth entered the lattices of the carbon atoms, thus determining their color mutation. For example, nitrogen produces shades of yellow while boron leads to bluish shades. Nature teaches that perfection does not exist.
Their market value is determined by the intensity of the color and they represent an example of error of nature which becomes an absolute value.
