Color with reference to diamond grading refers to subtle differences in the body color or hue. The distinctions between color grades within the normal range are quite subtle and virtually undetectable to the untrained eye. Another way to visualize the subtle difference between the color grades is to take a clear glass of water and add a few drops of yellow food color. Each drop of color will result in a subtle warming of the waters body tone. In diamonds, such subtle differences in color can make the difference of hundreds or thousands of dollars in price per carat.
Diamonds are naturally available in almost every spectrum of the rainbow.
However, the average consumer thinks of diamonds as white or colorless. F. However, most experienced graders can see color in these diamonds when they are unmounted. Most consumers can identify a color difference in diamonds that grade K,L,M in mounted diamonds that weigh one-half carat or more. However, they often mistake mounted K,L,M diamonds weighing less than half a carat as being colorless when they are mounted in white metal. Although yellows are more easily identified by consumers, brown and gray tones are also graded on the same scale.
