What AGS Laboratories does
AGS Laboratories is the laboratory division of the American Gem Society, a nonprofit trade association founded in 1934 and headquartered at 8881 W. Sahara Ave., Las Vegas, Nevada. The organization is dedicated to consumer protection in the fine jewelry industry and operates with 101-250 employees, providing independent third-party diamond grading services, professional credentials and designations for jewelers, gemologists, appraisers, and sales associates, and educational programs covering diamond grading and gemology.
The organization's core technical asset is the proprietary AGS 0-10 Diamond Grading System, a numeric scale (0 = highest, 10 = lowest) that evaluates diamond quality across Cut, Color, Clarity, and Carat Weight. This methodology underpins AGS Laboratories' diamond grading reports and provides an alternative to the traditional D-Z letter-based color grading system. Supporting products include the Find a Jeweler consumer directory, the 4Cs diamond education resources, a comprehensive birthstone reference library, and the AGS Member Portal for credentialed professionals.
AGS makes money through four primary streams: business membership dues (Retail, Partner, and Emerging Designer tiers on annual billing), individual membership dues from credentialed and affiliate professionals, education and credentialing fees delivered via the AGS PRO education portal, and professional services revenue from diamond grading laboratory reports. Distribution is indirect, operating exclusively through a domestic U.S. member network of credentialed jewelers and gemologists rather than direct consumer sales. Engagement is driven through annual Conclave and Confluence events, monthly Discover AGS Zoom Q&A sessions, content marketing, and social media presence across Facebook, YouTube, Pinterest, and Instagram.
