The history of AGS can be traced back to the 1920s, at which time Robert M. Shipley was an influential jewelry merchant. He experienced a very humbling but awakening experience one day. During his heydays as a jewelry seller, Shipley believed he was the best merchant around and thought that he knew everything there was to know about jewelry in general. But that was before a pair of his repeat customers proved to him otherwise.
Shipley took the challenge positively. He reckoned that the apparent lack of expertise among many jewelry merchants accounted for the growing distrust between traders and their customers. When he later divorced, he ended up losing his jewelry store. Shipley then moved to Europe with one sole motive—to learn more about jewelry. As soon as he got there, he enrolled in a correspondence course with the Great Britain National Association of Goldsmiths. Upon completing the course, he traveled back to LA with a wealth of gemological knowledge and experience.
On 16 September 1930, Shipley founded a preliminary course in gemology. He focused all his time and energy on training local gemologists. During his training programs, Shipley introduced and fostered a somewhat new concept in the jewelry industry. The focus would not be profit generation but exceptional customer service. It is from his efforts that the phrase “certified gemologist” came into existence.
Shoppers were now keen on dealing only with certified gemologists, creating a ripple effect that forced more traders to enlist for Shipley’s training programs.
Since the 1930s, the AGS has been on a consistent growth trajectory. The organization has introduced some globally accepted concepts and practices in the jewelry trade. Some of these achievements include:
- The invention of the first scientifically reviewed Cut Grade method.
- The creation of the Ideal Cut Grade for use on Round Brilliant diamonds, commonly referred to as the Triple Zero Cut or the AGS Ideal.
- Offering the first diamond grading reports with Oval and Emerald cuts, including a Cut Grade for Princess.
