SSEF Swiss Gemmological Institute: What to Expect
SSEF is a leading Swiss laboratory specialising in advanced testing and origin opinions for high-value coloured gemstones and pearls.
Scientific rigor
SSEF uses advanced spectroscopic and trace-element analysis to identify treatments and offer origin opinions, particularly for ruby, sapphire, emerald and natural pearls.
Facette reports
SSEF publishes research through its Facette newsletter, reflecting ongoing refinement of origin and treatment detection methods as new deposits and treatments emerge in the market.
Using the report correctly
An SSEF report states findings as of the examination date using current science; it should be read as an expert opinion, and buyers should verify report numbers directly with SSEF for significant purchases.
Buyer checklist
- ✓ Verify the report number with SSEF directly for high-value stones
- ✓ Check the report date given that gemology testing methods evolve
- ✓ Confirm treatment disclosure wording before assuming a stone is untreated
