In the exciting world of gemstones, the Fancy yellow diamond stands out among the rest with its unique beauty and richness. Fancy yellow diamond is a category of diamonds with an intense yellow color that does not fit into the standard color scale of colorless diamonds. Its color is a result of the high nitrogen content in its crystal lattice. Nitrogen plays an important role in the formation of the color of diamonds. It is often found in colorless diamonds and depending on its concentration, they can take on different shades of yellow or brown. The difference between them and the Fancy yellow diamond is in the distribution of nitrogen in their crystal lattice. Most diamonds do not have enough available nitrogen atoms to give them an intense yellow color. This happens when the atoms are scattered throughout the stone instead of clustered or paired. The color scale for determining the value of colorless diamonds ranges from color D(diamond) to color Z, with the latter having the lowest color quality. Outside this scale fall Fancy color diamonds, which nature has created in perfectly bright and interesting colors: blue, green, pink and of course - yellow. The yellow color is one of the rare Fancy color diamonds, beautiful enough to be valued. 
The grading scale for Fancy yellow diamonds is different from the standard color scale used for colorless diamonds. These are considered in a special scheme called the Fancy Color Grading Scale, which is used to determine the intensity and saturation of the yellow color.
Within each category of the Fancy Color Grading Scale, diamonds can have different shades and intensities of color. Fancy yellow diamonds are graded by gemologists with special skills and experience. It is important to note that the color grade of a Fancy yellow diamond is only one of the factors that affect its value.Its purity, polish and carat are equally defining and important.
All information about your diamond can be found in its exchange certificate of quality and origin. When choosing such a specific and rare gem, the presence of a diamond exchange certificate guarantees its authenticity and value, as well as its natural origin.
