Are Yellow Diamonds Less Valuable. With yellow diamonds you are more likely to find a stone that suits your budget than you would be for most other colored diamond varieties. However each diamond is different and its values are what determine its rarity - usually the weak tints are less rare whereas yellow diamonds with strong hue and saturation are considered very rare such as the Fancy Vivid Yellow diamond.
Most yellow diamonds on the lower end of the intensity chart are generally cheaper than colorless diamonds. Since yellow diamonds are so popular they often cost more than average colorless diamonds of comparable. It is as if the yellow scale starts when the white-diamond scale ends.
This rule holds true for all natural fancy color diamonds.
The simple answer to this question is that yellow diamonds are more expensive because the stone is more rare compared to the clear diamond however with most things in life there is never a simple answer to a good question. You cant judge one gem species as the most valuable. When the yellow color is obvious and attractive the diamonds will be valuable and highly desirable. So esentially the Clarity of a yellow diamond graded between Internally Flawless and VS2 has little or no impact on the value of the diamond.
