Like any other gem, diamonds come in different colors but in a white diamond, the presence of a yellow tint will lower the price of loose diamonds.

A subtle difference in color can dramatically affect its value. Colorless diamonds are the rarest making them the most expensive.

The Color Grading Scale

Diamonds that ranges from colorless to light yellow fall within the normal color range. The diamond color scale starts with the letter D and ends with Z. D-colored diamonds have the least amount of colors while Z colored diamonds have the most color. As diamonds are closer to D on the measuring scale, the more expensive they will be. Beyond the Z color, diamonds are graded as Fancy Color, which uses a separate set of parameters.

For a diamond to be more precious, they must reflect all the shades of color. Any color tint in the diamond will obstruct this. Thus, the less color there is, the more will it reflect other shades of color. Colorless diamonds are very rare. They contain little to no impurities and are essentially chemically pure. As the diamond shows more tint of color, it goes down the color grading scale.

Factors That Affect The Diamond Color?

Once a stone is set in a ring and placed in an environment that contains color, it will become much harder to detect its color. An H color diamond may look as colorless as a D when set in a ring under normal lighting conditions.

The color of the mounting itself also affects a diamond’s apparent color. White metal mountings make the color in yellow diamonds more apparent while yellow gold makes slight amounts of yellow in a diamond less obvious.

Many people cannot distinguish a color grade. Diamonds are color graded under controlled conditions by comparing them to round brilliant diamonds of known color.

If you have questions about color or other aspects of a diamond, ask a diamond consultant or your local jeweler. Ensure you are speaking to a reputable jeweler.
