Understanding the 4Cs
a quick guide
Before you buy, here's what the 4Cs mean for your diamond and why each one matters.
01 · Cut
Sparkle & Brilliance
Excellent or Very Good cut grades give the most fire and light return. Cut is the most important of all the 4Cs — it defines how the diamond catches light.
03 · Clarity
FL (flawless) to SI2
For most jewelry, VS1–VS2 offers excellent clarity that looks perfect to the naked eye — at a much better price point than Flawless.
02 · Color
D (colorless) to Z (yellow)
D–F is colorless. G–J is near-colorless and excellent value. For colored diamonds, a stronger, more vivid hue is more desirable.
04 · Carat
Weight of the Diamond
Bigger carats = higher price, but cut and clarity matter more for beauty. A well-cut smaller diamond will outshine a large poorly cut one.
