In white diamonds, Color actually measures the absence of color. The closer a diamond is to being completely pure and colorless, like a drop of pristine spring water, the greater its brilliance, rarity, and fire.
The International D-to-Z Color Scale
Graded under controlled laboratory lighting by IGI and GIA, diamond color ranges from D (completely colorless) to Z (noticeable warm yellow or brown tint):
| Color Grade | Category | Visual Characteristics |
|---|---|---|
| D - F | Colorless | The highest standard of icy, pure transparency with zero visible tint. CHOW HENG FOOK center stones are curated in this top tier. |
| G - J | Near Colorless | Appears face-up white to the naked eye; excellent value when set in yellow or rose gold. |
| K - M | Faint Tint | A subtle warm yellow tint is detectable without magnification. |
| N - Z | Light Tint | Visible yellow or brownish body color. Not curated by CHOW HENG FOOK. |
