Diamond evaluation is set by the 4 most important parameters of the diamond, Color, Clarity, Cut and Carat weight. This main 4 parameter collectively termed "the 4C's". When you combine all these parameters in a specific diamond, then you can define the diamond quality and understand the value of this diamond. Any change in each parameter has a significant effect on the diamond quality and value, this is why it's very important to understand the 4C's before buying a diamond. That way, you can purchase the exact diamond that fits your desire and your budget.
The creation of the 4C's helps to communicate in universal language, that way, diamond purchasers know exactly what they are buying.
1. Diamond Color
Diamond color can be different between diamonds, in the picture you can see the scale from D color (colorless), the highest color in the scale, to Z color the lower one (yellow).
As the diamond color moves up in the scale to D color, means the diamond have better quality in color parameter.

2. Clarity
Natural diamonds are from carbon and exposed to huge heat and pressure deep in our earth. Diamonds often contain clarity characteristics that called inclusions.
Inclusions are enclosed within the gem.
The closer a diamond is to flawless (the highest clarity in the scale) that means that quality and value are higher.

4. Carat Weight
Diamond weight is measured in carats.
One carat equal to 0.20 grams. If the diamond has the same color, clarity, and cut grades, but the weight is higher, then the same diamond will cost more.
