The American Gem Society (AGS) 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. Only one in twenty jewelers have met the exacting requirements necessary for membership. To join the 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.
