Which white diamond color is more valuable?

The more colorless the diamond, the more unique and expensive it is.

Well, that’s true. The GIA Color Scale helps gem lovers to determine a diamond’s color quality and its level of transparency.

GIA developed the Diamond Color Chart in the early 1950s. At that time there were a lot of different subjective terms used for describing a stone’s shade: for example, white, blue white or AAAA.

The GIA scale begins with D, which represents total transparency, and continues with increasing presence of color to letter Z, which stands for light yellow/brown/gray. Each letter is a measure of how noticeable the hue is. The 23 color grades on this Color Chart are subdivided into five subcategories:

Colorless (D, E, F)

Near colorless (G, H, I, J)

Faint color (K, L, M)

Very light color (N-R)

Light color (S-Z)
