Four C's of Diamond Buying

The cut of a diamond has a tremendous affect on its brilliance. Even if the diamond has perfect color and clarity, a poor cut can make a diamond look dull.

Colorless and near-colorless diamonds are most highly valued and are priced accordingly. Other diamonds may have a slight tint of color, and some can even have a readily noticeable tint, which can diminish the brilliance.

Diamonds completely free from internal flaws, or inclusions, are very rare and highly valued. Clarity is graded based on the number, location, size, and type of the inclusions found in a diamond.

Carat Weight
The weight of a diamond is measured in carats. Since larger diamonds are more rare than smaller diamonds, diamond value tends to rise exponentially with carat weight.
