The Color of the Diamond 

The color of the diamond actually means a lack of color.

Understanding what a diamond's color means can help you choose the right diamond. Interestingly, the diamond color rating for most gem-quality diamonds is based on the lack of color. A chemically pure and structurally perfect diamond is of higher value because it does not have the hue of a pure drop of water. The D-to-Z diamond color grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to a master stone of established color values.

Many of these color differences in diamonds are so subtle that they are invisible to the untrained eye. However, these differences make a big difference in diamond quality and price. Therefore, it is important to consult an Efjewel expert to determine the best color for your diamond.
