Problem
Buyers, sellers, and insurers in the coloured gemstone market often lack reliable, independent analysis of a stone’s identity, origin, treatment status, and colour quality, leading to disputes, misvaluation, and reduced trust in transactions.
Solution

Expert senior gemmologists evaluate each sample, cross‑referencing results against a proprietary reference database and SIG‑AI models to ensure accurate identification, trace‑element origin profiling, treatment detection, and colour grading. Reports include high‑resolution imagery, complete disclosure, and secure online verification, providing transparent documentation for all market participants. The end‑to‑end workflow—from sample submission in Lucerne or Hong Kong to rapid digital delivery—prioritises efficiency, traceability, and consistency across the global value chain.
