What is the typical range for diamond color grading?

The typical range for diamond color grading extends from D to Z, which is represented by option A. This grading scale is widely used in the gemological industry to assess the presence of color in diamonds.

Diamonds graded from D to F are categorized as colorless, meaning they exhibit no noticeable color. As one moves down the scale to G through J, diamonds are considered near-colorless, displaying very slight traces of color that are often imperceptible to the untrained eye. From K to M, diamonds show more noticeable color, and those rated from N to Z gradually intensify in color presence.

The other choices, representing numerical scales or ranges such as 1 to 10, 0 to 100, or 1 to 5, do not correspond to the standard practices used by gemologists for color grading in diamonds. The established D to Z scale allows for a systematic and consistent evaluation of color quality, which is essential for determining a diamond's value and desirability.
