The color of a white diamond


From perfectly translucent to lightly tinted – a diamond’s color scale.

Diamonds not only come in different shapes and sizes, but also colors: There are diamonds in shades like blue, pink and even black. However, the diamonds used for engagement rings are mostly white diamonds.

The GIA grades white diamonds on a scale from D for an absolutely colorless diamond to Z for a yellow or brownish tint:


  • D
  • E
  • F

Near colorless

  • G
  • H
  • I
  • J


  • K
  • L
  • M

Very light

  • N
  • O
  • P
  • Q
  • R


  • S
  • T
  • U
  • V
  • W
  • X
  • Y
  • Z

Why does the color scale start at D?

Before the GIA established their scheme of assessing diamonds by the 4C in the 1930s, multiple rating scales were used. Among them was an A-B-C scale, where multiple as marked the best stones. The creators of the GIA color scheme wanted to avoid confusion and therefore let the scale start with a D.

What’s the minimum color grade I should go for?

The colors grade affects the overall appearance. The larger a diamond, the more apparent the color grade. Read more on the right trade-off between the 4C color, cut, clarity and carat here.
