Summary
Many buyers judge fancy colored diamonds by the same 4Cs used for colorless stones. In reality, colored diamond grading prioritizes color intensity and rarity. Learn how to evaluate hue, brilliance, and value properly.
Colored Diamond Grading Explained
When you buy a diamond, you probably think about the 4Cs — Cut, Clarity, Color, and Carat.
However, that system was designed for colorless diamonds, not colored ones.
In colored diamond grading, color takes the lead. Clarity and cut support the overall appearance of the stone.

How Color Determines Value
Color is the heart of every fancy diamond.
The more intense the hue, the higher the value.
- Fancy Vivid and Fancy Intense grades command premium prices.
- Even a smaller vivid pink can outprice a larger faint pink.
Think of colored diamond grading like judging a painting — you pay for the richness of the color, not for minor canvas imperfections.

Cut and Clarity Support Color
A diamond with minor inclusions can still rank high if its color is exceptional.
Cutters often choose shapes — like radiant or cushion cuts — that enhance face-up color, not just brilliance.
A Buyer’s Perspective
Ask yourself:
- Would you reject a vivid blue diamond due to a tiny mark?
- Would you choose a flawless faint yellow over a vivid yellow?
Your answers reveal how color dominates grading decisions.

Key Takeaway
When evaluating colored diamond grading results:
- Start with Color
- Treat Clarity and Cut as secondary
- Focus on hue intensity, visual impact, and rarity
Most grading mistakes happen when buyers apply the 4Cs of colorless diamonds. In fancy-colored diamonds, Color drives beauty, rarity, and price.
