GIA is an American Gemological Institute with a global scale comparable to IGI, which was first established in the United States in the 1930s. But the real large-scale development was in the 1950s, which happened to be the period of great development of American industry and consumption. Therefore, there is an urgent need for a unified standard that can be replicated on a large scale to meet people's large demand for diamonds.
GIA summed up the previous experience in a forward-looking way, systematically put forward the concepts of "clarity" and "color" used by merchants in the previous industry when selecting gems, and formally put forward the 4C statement in the 1950s, which played an important role in the rapid development of the jewelry industry in the future, and in the following time, many instruments for analyzing gems were also introduced, which facilitated people in the industry to identify gems more efficiently.
