Video: History of the 4Cs

The 4Cs – color, clarity, cut, and carat weight – describe a diamond’s appearance, define its quality, and greatly influence a diamond’s value. But did you know that before GIA established the 4Cs in the 1940s, there was no agreed-upon system by which diamond quality could be communicated?

Our exclusive video takes you through the history of the 4Cs, and explains why they remain the universal standard for assessing your diamond. Watch it, and tell us what you think!
