About SSEF

The abbreviation SSEF stands for “Schweizerische Stiftung für Edelstein-Forschung,” or in English: Swiss Foundation for the Research of Gemstones.

SSEF – Swiss Gemmological Institute was founded by trade organizations (UBOS: Union de la Bijouterie et Orfèvrerie Suisse) on August 22, 1972. It is an internationally recognised authority in the testing of gemstones and jewellery. It operates independently on a scientific basis and has been setting standards in gemmological research over the past 50 years.

The foundation is under the aegis of the Swiss Federal Department of Home Affairs and is supervised by a foundation board comprising Martin Häuselmann (President, Bern),  Charles Abouchar (Geneva), Walter Balmer (Bern), Horst Edenhofer, Christiane Farah (Geneva), Ida Färber (Geneva), Christophe Stucki (Geneva), Frederic Torroni (Geneva) and Melissa Wolfgang Amenc (Geneva). The laboratory is directed by Dr. M.S. Krzemnicki.

SSEF’s function is to analyse precious stones and issue test reports for diamonds, coloured stones, and pearls. It was recognized in 1978 by the World Jewellery Confederation (CIBJO) and is also a member of the International Colored Stone Association (ICA) and the Laboratory Manual Harmonisation Committee (LMHC).

Today, SSEF is one of the world’s leading gemmological labs, especially for high-end coloured gemstones, diamonds, and pearls. All SSEF laboratory members are gemmologists with scientific and gemmological education and international backgrounds. With years of experience, they uphold the highest level of integrity. Engaged in research and education, they collaborate with universities, gemmological laboratories, and research institutions worldwide.

Equipped with cutting-edge analytical instruments, SSEF ensures that the authenticity of gemstones, origins, and possible treatments are tested scientifically and reproducibly. SSEF is the trusted lab of precious stone dealers, jewellers, auction houses and royal families. SSEF’s laboratory primarily examines loose cut stones but also tests stones set in jewellery.

Gemmological test reports are written in English, French, or German, with an option for Chinese versions. All reports are for identification only and do not provide a commercial evaluation.

Since 1972, SSEF has been committed to sharing its expertise and practical skills by offering intensive and efficient courses at all levels of gemmology.
