Although the diamonds that we are familiar with are white, not all of the diamonds are white. As you know, diamonds are created under pressure in extremely high temperatures in the depths of the earth, and sometimes in the natural creation process of the diamonds different particles get stuck inside of them and affect all the chemical process of the creation of the diamond. When that happens, colorful rare diamonds are created naturally. The diamonds can come in a variety of colors, depending on the chemical process of their creation. You can find diamonds in shades of brown, red through pink, blue, green, purple, yellow through orange (all the basic colors). The color of the diamond affects its value; some colors that are considered rare, like blue or red diamonds can increase their value by millions of dollars, but on the other hand, different colors like a pale shade of yellow or a shade of brown, can be considered flaws, and lower the value of the diamonds. The colorful diamonds are called fancy diamonds, and they have great value.
There is a rating system that is accepted by diamond color rating labs, and the system pays attention to regular diamonds that are not considered colorful diamonds, and it rates them on a scale that starts with the letter D, representing a colorless diamond, and ends with the letter Z, that represents a pale shade of yellow or brown.
The color scale
- Colorless- D, E, F, G
·Near Colorless- H, I, J
·Faint yellow- K, L, M
·Dark yellow- N-Z
The shining of the diamond (the fluorescent one)
The fluorescence of the diamonds is a quality of the diamond that makes it shine when exposed to x-rays or to ultraviolet radiation (2 kinds of radiation that we are incapable of seeing). The diamond has different levels that verify from diamond to diamond, and it can be seen in different colors, like white, yellow, red, green or blue shining (the popular color of shining is blue, and the rest are considered rare). Some diamonds don’t shine, and some shine very brightly. There are five levels of shining that can be identified in a lab- non-fluorescent, slightly fluorescent, medium, strong, very strong. Bright shining can give the diamond a desirable look, but mostly it lowers the value of the diamond because it gives the diamond a cloudy look under direct sun. On the second hand, yellowish or brownish diamonds can look whiter with fluorescent if you look at the surface of the diamond (from the direction of the board). In the past, diamonds with strong fluorescent were fashionable and desirable, and in some cases, this quality added to the value of the diamond.
- In diamonds rated D-Z the more the body of the diamond is colorless, the more it’s valued.
- Diamonds rated under Z are fancy Diamonds and sometimes their value is higher than the value of colorless diamonds. There are rare colors in shades of green, orange, blue, red, pink, purple, which are valued up to tens of millions of dollars.
