However, the differences in the colors are quite subtle at times and it requires a trained eye to notice one color grade differences in diamonds. The difference in color grades can be thought of as differences in the whiteness of paper. For example the difference in whiteness of a facial tissue, a local newspaper, a sheet of computer paper, and a small index card is minor but the color difference does exist. Also, the color in diamonds can be either yellow (in most cases) or brown.

The color grade ranges from D - Z color, where D is the whitest (or colorless) and Z is light yellow or brown. The more whiter, or colorless, a diamond is the rarer it is and thus more valuable it is. D-F, colors are viewed as colorless and are very rare, where G-I colors are near colorless and still rare.

J-K colors have very light color but are ideal for yellow gold mountings because diamonds in these mountings still look white because of the surrounding. Colors below K are not advised by GemsNY because they have traces of color which can be detected by an untrained eye. GemsNY carries diamonds in color grades from D-K color only. We don't carry colors below K to ensure you are selecting the highest quality diamonds.

Diamonds which have more color than Z, are viewed as Fancy Color Diamonds . These diamonds are graded different from white diamonds. In fancy color diamonds, unlike white diamonds, the more intensity of the color in the diamond the more rarer it is and thus more expensive it is. GemsNY carries Fancy Color Diamonds
