Diamond Color Explained: Choosing the Right Shade

Most diamonds appear colorless - but small differences in color can have a big impact.

The Diamond Color Scale

Diamonds are graded from D to Z:

• D-F → colorless (‘icy’ look)
• G-H → near colorless
• I+ → (slight) yellow tint

Why Color Matters

Less color means more light reflection, resulting in:

• brighter appearance
• more brilliance
• higher value

What Should You Choose?

D-F offers the highest quality. G-H offers excellent value with minimal visible difference.

Why doesn’t diamond color grading start from A, but from D?

You might expect diamond color grading to start at the letter A - but in reality, it begins at D.

This isn’t random. Before the modern grading system existed, different jewelers used their own inconsistent scales, often starting at A, AA, or even AAA to describe top-quality diamonds. This created confusion and made it difficult to compare stones objectively.

To solve this, the Gemological Institute of America (GIA) introduced a completely new and standardized system.
They intentionally started at D to clearly separate their scale from all previous, unreliable ones.

Color is subtle - but once you notice it, it changes everything.
