There is a common false impression that anatural yellow diamond is less valuable than a colorless diamonds. Even though very light or slightly yellow diamonds are considered to be quite typical and not of high value, yellow diamonds for example intense and vivid are really quite valuable.
Natural yellow diamonds with secondary brown tones are worth considerably less than pure yellow stones. However, secondary colors of green-yellow or orange-yellow can considerably increase the value of the stone due to the fact that these diamond colors are even scarcer than fancy yellow diamonds.
Fancy color yellow diamonds are rated by their strength and intensity of color. The highest-quality grade is the Vivid Yellow, closely followed by the Intense Yellow diamond. The lowest quality of natural yellow diamond is the Light Yellow diamond, closely followed by the Fancy Yellow. A number of tones of Vivid Yellow diamonds and the rarer Intense Yellow diamonds are called Canary Diamonds. Canary diamonds are the most rare amongst yellow diamonds and thus they are the most costly and are desirable both by collectors and sophisticated customers. The canary diamond has a very special tone of yellow, even if you have never observed a Canary Yellow, once you see it, you will realize that it is a Canary Diamond.
Yellow diamonds look wonderful when they are combined with white stones and typically yellow diamonds are set in yellow gold. A 3-stone ring should include white diamonds and the yellow stone should be set in the center. A beautiful setting is a fancy yellow diamond with trapeze, triangle or oval white diamonds..
Like in other natural fancy color diamonds the coloration remains the main thing that influences how much the diamond is worth, then comes size and of course clarity. Clarity is also important in evaluation of fancy yellow stones, though much less than in white diamonds.
Fancy colored diamonds are most often found in a Radiant cut. This is considered the ideal shape for increasing the color. Yellow diamonds, however, can also be found in Oval Cut an Cushion cut and in Heart and Pear shapes. The rarest are the Emerald, Square Emerald and the Brilliant cuts (round shape). Prices of these shapes are considerably higher for all fancy diamonds and not merely for yellow diamonds.
The cut quality of a colored diamond is very different to the traditional diamond. The goal when cutting a color diamond should be to emphasize the depth and saturation of the diamond's color while striking a balance between the carat weight and brilliance. It is critical that the stone is sold with a grading report from a reliable diamond laboratory such as GIA, HRD, IGI or EGL. The report needs to state that the color is "Natural". The report should also describe the intensity of color, in addition to the color distribution throughout the stone.
The Kimberley Octahedron is the biggest naturally formed actohedral diamond in the world. The owner of the mine has decided against cutting this diamond at alland wishes to keep it in its original condition. Due to this the color and distribution grades cannot be given to this magnificent diamond.
