Fancy color diamond refers to a diamond with a distinctive color, or a rare natural color diamond, which belongs to the list of colored diamonds and is very popular among people. In the case of yellow or brown diamonds, the color must be of sufficient depth. For example, in the GIA classification system of the international appraisal grading system, it must be deeper than the Z color color stone to be called a colored diamond.
Diamonds of other colors, although lighter in color or lower in color saturation, can still be called colored diamonds. Among the colored diamonds, red and green are extremely rare, followed by reddish purple, purple, orange, pink and blue. The colored diamonds in the jewelry market are mainly yellow and tan, and the former is more economical.
The degree of color is usually graded according to color saturation <chroma> and hue <shading> and the color of the diamond is used. These terms are placed before the body color, such as Fancy yellow <color yellow> or Deep yellow <dark yellow>. The color diamonds certified by GIA are of great value in the jewelry market.
