The American Gem Society
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, re-certification of its membership, gemological standards, and gemological research.
The American Gem Society’s Pledge to the Consumer
The American Gem Society (AGS) was created with one mission in mind: to protect you, the consumer.
Our members adhere to the highest standards of business practices and ethics so that you can buy with confidence from jewelers you can trust. AGS Standards not only comply with governing laws; but go beyond that to ensure that you are buying from jewelers who have the knowledge and skill to help you make the most informed buying decision.
Why Choose an AGS Jeweler?
What do the initials behind a jeweler’s or appraiser’s name mean? If the credentials are earned through the American Gem Society, they mean a lot. In fact, only 5% of jewelers, designers and appraisers have met the American Gem Society standards.
Our titles and designations were developed to help you know the qualifications of someone who works in the jewelry industry. Our members must adhere to the American Gem Society’s code of ethics and are required to re-certify their title or designation each year.
When shopping for diamonds, gemstones, or jewelry, you can put your trust in the knowledge, experience, and integrity of a credentialed American Gem Society member.
