AI gemstone grading: Swiss lab launches SIG-AI to speed and standardize reports

Swiss International Gemlab (SIG) has launched a new AI gemstone grading workflow, aiming to improve accuracy and consistency in colored gemstone testing. Founded by veteran gemologists Willy Bieri, Lawrence Hahn, and Matthias Alessandri, the facility will operate in Lucerne (Switzerland) and Hong Kong. At the core is “SIG-AI Assistance,” a proprietary system that cross-references analytical results with structured databases to flag inconsistencies and support uniform reporting. SIG says the platform helps shorten interpretation time and provides more transparent, science-led grading. SIG will offer full-service colored gemstone testing, including identification, origin determination, treatment analysis, and detailed color grading. The standard turnaround time is five business days, with expedited options for urgent submissions. Clients will also receive real-time tracking for report progress. SIG is set to make its first public appearance at GemGenève in May, offering on-site gemological services and a preview of its workflow. This launch follows a broader shift toward AI gemstone grading across the gemology sector, where labs increasingly use data-driven tools (including digital platforms and machine-learning analysis of spectroscopic data and high-resolution imagery) to strengthen verification standards and buyer confidence. For crypto traders, this is not a direct market catalyst for major tokens, but it is consistent with the ongoing adoption of AI-assisted verification tools across traditional industries.
