The 4Cs
How Diamonds Are Graded?
Understanding the 4Cs helps you choose the right diamond.
Cut - The Most Important Factor
Cut determines how light interacts with the diamond.
A well-cut diamond reflects light to create:
- Brightness
- Sparkle
- Fire
Even a perfect diamond will look dull if the cut is poor.
Recommended: Excellent / Very Good
Color - How Colorless It Is
Diamonds are graded from D (colorless) to Z (noticeable color).
- D–F: Completely colorless (premium)
- G–J: Near colorless (best value)
- K+: Slight yellow tone
👉 Most customers choose G–H for the best balance.
Clarity - Internal Features
Clarity refers to natural internal characteristics called inclusions.
Most are invisible without magnification.
- FL / IF: Flawless (very rare)
- VVS / VS: Very slight inclusions
- SI: Slight inclusions (often eye-clean)
- I: Visible inclusions
👉 “Eye-clean” diamonds offer the best value.
Carat - The Weight
Carat measures the weight of a diamond.
- 1 carat = 0.2 grams
- Larger diamonds are more rare and valuable
👉 Size appearance also depends on cut, not just carat.
