Loose Diamonds

Diamonds are based on their cut, color, clarity and carat weight.

To set up a diamond's superiority, jewelers examine each of the 4C’s -- cut, clarity, carat weight and color. The combination of the 4C’s determines the value of a particular diamond. For example, a colorless diamond is at the top of the Diamond Quality Pyramid in color ... but if it lacks clarity, is small, or not well cut, it will be of a lower value. The finest stones possess the rarest quality in each of the 4Cs, and are the most valuable.
