Base Colors: Diamonds are available in shades of 12 base colors. This includes red, yellow, orange, green, blue, pink, purple, brown, violet and gray.
In addition, black and white diamonds are also available. The shades of these hues also play an important role. A deep red diamond can look very different from a vivid red diamond.
Intensity of Color: Diamonds in each base color can be further classified based on the intensity of color. There are 9 levels of color intensity. This ranges from faint to fancy vivid. The in-between levels are fancy intense, fancy deep, fancy dark, fancy, fancy light, light and very light. Not all colored diamonds are available in all levels of color intensity. For example, faint, light and very light red diamonds are not available.
Similarly, there are no light yellow diamonds. Secondary Colors: Most colored diamonds cannot be described on the basis of a single color. Instead, they are usually described as a combination of two colors.
For example, orange-red diamonds, purplish pink diamonds etc. In some cases, a diamond could even be described as a combination of three colors. For example, it can be a yellowish grey-green diamond. In this case, a weak presence of yellow may be noted in the grey-green diamond. It is important to note that the dominant color is usually mentioned last. For example, when speaking of a blue-green diamond, green is the dominant color. When it comes to cutting colored diamonds, the best cut is one which makes the face color most attractive.
Thus, it is more important for a cut to maximize color intensity rather than brilliance. For this reason, most colored diamonds are cut in fancy shapes. This includes oval, pear-shaped, cushion and radiant cuts.
Unlike the case in colorless diamonds, carat weight does not play as important a role in determining the ideal cut. Thus, even though the round cut may result in less weight loss, a fancy cut may be a better choice. Irradiation is often used to make the black color look solid; a natural black diamond will have a salt and pepper look under magnification.
An oddity in the fancy colored diamond world is called the Chameleon diamond. These are typically olive green and can temporarily change color to greenish-yellow when exposed to heat or kept in darkness and then exposed to light. The canary diamond is magnificent. The other colours are admirable and very attractive. It just shows the importance, rarity and how precious diamond could be.

Natural Colored diamonds are created in the same fashion, with one unique difference.
When foreign particulates are trapped during the crystallization process from which diamonds are formed, it effects and alters the chemical process and thus, changes the outcome. The result is a beautiful, rare, and exceptional diamond with unique colorings - called natural colored diamond.
Different trace minerals and particulates result in different hues, as well as different intensities of those hues. Want to share the graphic? OR Tweet. These diamonds owe their color to a combination of intense pressure and heat. While still buried deep within the earth, these factors cause distortions in the crystal lattice that absorb green light, thus reflecting a pink hue. Ultra-rare red diamonds, which are essentially just deeply colored pink diamonds , have the same cause of color.
For the most part, blue diamonds get their color from boron. When this impurity is present, it bonds to carbon in the crystal structure, absorbing red, yellow and green areas of the color spectrum. It's not until the last leg of their journey to the earth's surface that diamonds get their green color. Just as they are about to leave the uppermost layer of the crust, these stones absorbs naturally occurring radiation, which causes them to reflect a green hue by absorbing red and yellow light.
So far, all scientists are certain of is that the cause of color for purple and violet diamonds is crystal distortion.
