AGS Unveils Diamond Quality Certificate

The American Gem Society and American Gem Society Laboratories unveiled a new diamond quality certificate Tuesday at the organization’s International Conclave in Denver, Colorado.

According to the AGS, the DQC “is a guarantee of authenticity and performance by the jeweler”, available only to its retail members.

“By publishing this signed document, AGS Laboratories’ DQC meets the legal definition of a certificate,” said Cecilia Garner, president and CEO of the Jewelers Vigilance Committee.

The American Gem Society is a not-for-profit trade association dedicated to ethics, knowledge, and consumer protection in the jewelry industry.

Less than five percent of jewelers in the United States have met its requirements for membership, the society says.
