Intoduction to the 4 C's
Introduction to the Four C’s of Diamond Assessment Video Summary
In the 1950s, a standard was developed to help jewelers and gemologists measure the quality of diamonds. This universal standard, created by the Gemological Institute of America became known as the four C’s because of the four characteristics by which the gems are measured. They are cut, color, clarity, and carat weight.
This is the established system by which diamonds can be evaluated. The first two C’s, color and clarity, are known as “rarity factors” because these are determined by their natural formation. A high color and clarity grade means the diamond is rarer and therefore more valuable. Clarity and carat weight, on the other hand, are determined by the diamond cutter. Each of these four characteristics are important factors to consider when choosing a diamond.
