The Four C's of Diamonds
To establish a diamond’s quality, you must understand the global standard for diamond quality: Cut, Color, Clarity, and Carat. The overall combination determines the value and beauty of a diamond.
Diamond Shapes & Styles
1. Diamond Color
The less color a diamond has, the more valuable it becomes. The scale ranges from D (colorless) to Z (light yellow).

3. Carat Weight
A diamond’s weight, not size, is measured in carats. One carat is divided into 100 points, so a diamond of 75 points weighs .75 carats.
4. Diamond Cut
Cut determines radiance. A master craftsman releases the fire, sparkle and beauty of the stone.
