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.
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 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.
The American Gem Society (AGS) is a nonprofit trade association of fine jewelry professionals dedicated to setting,
maintaining and promoting the highest standards of ethical conduct and professional behavior through education,
accreditation, recertification of its membership, gemological standards, and gemological research.
The Society is committed to providing educational products to inform and protect the consumer and to contributing to the betterment of the trade by creating industry standards to protect the jewelry-buying public and the fine jewelry industry as a whole.
AGS Laboratories, founded to support the AGS mission, is a nonprofit diamond grading laboratory with a mission of
consumer protection. Adhering to the AGS Diamond Grading Standards, AGS Laboratories is dedicated to offering diamond grading reports that provide consistency and accuracy based on science.
