American Gem Society

Embee Diamonds, Byard F. Brogan and The Inspired Collection are all members of the American Gem Society.

Founded by Robert M. Shipley and several other leading jewelers and gemologists in 1934, the American Gem Society is a trade association of fine jewelers, industry professionals and suppliers in the United States, Canada, and select countries such as New Zealand. 

We are committed to consumer protection, ethical business practices, and the development of superior gemological skills and knowledge.

Before there was an AGS Laboratories, there were other diamond grading laboratories. However, their focus was on providing a service limited to the jewelry trade. The members of the American Gem Society, an elite group of jewelers bound by a mission of consumer protection, felt that the industry, as well as the consumer, would benefit from a laboratory held to a stricter standard of diamond grading — with a founding tenet of consumer protection first and foremost.

That mission in mind, they created the AGS Laboratories.
