About AGS

Robert M. Shipley

The American Gem Society was founded in 1934 by a small group of leading jewelers. Their goal was to create an organization that could help protect the jewelry-buying public from fraud and false advertising. Today, we’re proud to say their vision has become a reality.

Approximately 3,400 jewelers, retailers, suppliers, individual titleholders and affiliates have joined the American Gem Society and have dedicated themselves to consumer protection, ethical business practices, and development and maintenance of superior gemological skills and knowledge.

Only 1 in 20 jewelers have met the exacting requirements necessary for membership. To join AGS, every member must go through a peer-reviewed application process followed by an annual recertification exam. This process ensures that every AGS member you meet is at the top of their game, and more importantly, each one has pledged to protect you, the consumer.
