The Gemological Institute of America

The Gemological Institute of America has been, and continues to be, one of the largest forces in the unification of all aspects of gem research, education, classification, and collection. Founded in the early 1930s by Robert Shipley, the GIA’s goals were simple: to develop systems and methods to correctly classify and professionalize the industry. Since its inception, the GIA has become the premier resource for gem collectors, retailers, and scientist alike.

Among its most important milestones was the creation of the 4Cs and the international diamond grading system, which initiated a worldwide classification of diamonds. This idea then evolved into the GIA certification process. This process aims to certify as many gems as possible, from Green Tourmaline to Tsavorite Stones, through various characteristics such as clarity, carat, cut, and color, among other criteria. After decades of grading and certifying a vast array of gems, and even creating new technologies to help along the way, a GIA certification is now something that is sought after, and even required, by collectors of all types. It is now standard practice to check the status of a gem through the GIA to make sure every aspect of the gem is legitimate, from cut to area of origin. Color is now seen as the most important factor for a Gemstone and whether or not a particular gem can become certified–the gems pictured above are two of our finest examples of certified gems. Below is an example of what a genuine GIA Certification looks like!
