The diamond industry’s approach to laboratory-grown diamond detection has transformed significantly over the past decade. What began as a challenge of identifying undisclosed synthetic diamonds has evolved into a broader focus on product integrity, supply chain verification, mounted jewelry screening, and ensuring accurate representation of natural, laboratory-grown, and simulated diamonds.

Gemological Science International (GSI), one of the world’s largest gemological organizations, has identified undisclosed lab-grown diamonds in jewelry set with natural brown diamonds. The discovery comes at a critical time, as the global jewelry trade increasingly promotes off-color natural diamonds, such as brown and champagne hues, as unique, fashionable, and affordable alternatives to traditional colorless stones.
