Diamond Color

While shopping for a diamond, the colour of the diamond is an important characteristic. Interestingly, it is preferred to select a diamond with the least amount of colour, since a diamond that is chemically pure and structurally perfect has no hue. The colour of the diamond is graded on a scale from D (colourless) to Z (light yellow or brown) after analysing the stone under controlled lighting and other precise conditions. The diamond colour grades are divided into five broad categories - colourless, near colourless, faint, very light and light. The colour that is predominant in a diamond is yellow, caused by the trace element nitrogen.

While comparing the colour between two diamonds choose diamonds that are at least two colour grades apart to better understand the difference in hues. It will be nearly impossible to see any colour if you are viewing the diamond in the face-up position. However, as you view the diamond from its side profile you will be able to notice some colour; even though a diamond is always appreciated from the face-up position and not the side.

Colorless Diamonds (D-F):

The stones within D-F is said to be the most valuable and rare of all the diamonds. While the diamonds between D-E range are virtually colourless, the F coloured stones will show an undetected amount of colour while viewed face down by a professional.

Near Colorless Diamonds (G-J):

The near colourless range of diamonds might appear colourless to an untrained eye especially if the diamond has been mounted. However, it displays a slight hint of colour when viewed face down against a clear white background. These range od diamonds offer an amazing value of their price.

Faint Color Diamonds (K):

The diamonds under the faint colour range will display a trace amount of colour when viewed from the face-up position.

The most common colour found in a diamond is yellow. That said, at times you will be able to notice a brown colour in a diamond. This is because of the internal graining. Internal graining is the result of structural irregularities mainly caused by impurities like nitrogen.
