Diamonds from “D” to “Z”
In the article “The rainbow of diamonds” we saw how this precious gem can assume wonderful colors thanks to the presence of inclusions, reticular defects or atoms of elements that blend into the crystal lattice.
However, the diamond is more commonly known and appreciated as a colorless gem because most of the diamonds present in the jewelers are in fact like this: over time we have been “educated” to admire them precisely for this characteristic.
Actually, colorless diamonds are only a small part of the extracted diamonds: most of them show a more or less intense yellow tint, caused by the presence of nitrogen atoms inside the crystal lattice.
Color is one of the parameters throught which the diamond is classified according to its 4C, namely Cut, Carat, Clarity and Color. The color scale is commercially defined D-Z, where the diamonds classified as D are completely colorless while gradually, going down towards the Z, the coloring will increasingly become saturated towards the shades of yellow.
From Z and over, diamonds enter the classification of fancy color diamonds, i.e. those that have a color saturation so intense that they cannot be classified with the scale described above as they would be too penalized in terms of price.
Color is very important when you decide to buy a diamond as it will inevitably affect – together with the other three parameters – the final value of the stone. Commercially the most common colors are G and H, because they are the ones with the best quality-price ratio: although there is a yellow tint evident in the eyes of an expert, once mounted these diamonds appear as colorless as other diamonds with higher colors on the DZ scale (which would therefore cost a lot more).
For this reason, when you decide to buy a diamond, it is essential to rely on the expert hands of a competent person, who will be able to help you choose the best diamond for your needs, while also respecting your pockets.
