Origin of the Diamond 4C's

Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4C's of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.
