What are the 4Cs of a diamond?
Kurz gesagt:

The 4Cs of a diamond are Cut, Color, Clarity, and Carat. They form the globally recognized GIA grading system and together determine a diamond's quality and price.
The 4Cs at a glance
- Cut: Determines brilliance. The most important C. GIA scale: Excellent > Very Good > Good > Fair > Poor.
- Color: D (colorless) to Z (yellowish). G–H is optimal for most buyers.
- Clarity: FL to I3. VS2 is the best value for money – clean to the naked eye.
- Carat: 1 ct = 0.20 g. Larger weight = more expensive, but cut is more important than size.
Which C is most important?
Cut – always. A poorly cut diamond looks dull, no matter how large or clear it is. Invest in an Excellent or Very Good cut first.
