Diamonds exist in all colors of the rainbow, from dark brown to warm yellow, bright pink to enchanting purple, and intense red to deep blue. When a diamond has a pronounced, intense color, it is referred to as a “fancy color.” Colorless diamonds, more commonly known to the public as white diamonds, appear at first glance to have no specific color.

When studied more closely, these diamonds can show a slight yellow or brown tint. By comparing these diamonds to master stones, the exact color of each diamond can be determined more precisely. The less color a diamond is evaluated to have, the more valuable it becomes. For a diamond’s color, what you cannot see is actually what matters most. The less color, the higher the diamond’s value.

GASSAN’s color grading for diamonds follows the prevailing standards in the diamond industry. The scale begins with the letter D, corresponding to exceptional white+, and continues down to the letter Z, with the color intensity increasing from light yellow to brown. Each letter represents a clearly defined range in color grading.
These color nuances are often so subtle that they are almost impossible to perceive with the naked eye. On the other hand, these variations can make a significant difference in the quality and value of a diamond.
