An international research group led by scientists from the Swiss Gemmological Institute SSEF and the University of Zurich\u2019s Institute of Forensic Medicine (IRM) has reported a breakthrough in precious coral jewellery traceability, through the use of a novel forensically validated genetic technique called Coral-ID. The results of its research have been published in the leading peer-reviewed journal Forensic Science International: Genetics.<\/p>\n\n\n\n
Coral-ID is the first reliable and forensically validated method to scientifically identify corals using quasi non-destructive sampling, so that species protected by the Convention on the International Trade of Endangered Species (CITES) can be distinguished from their non-protected counterparts.<\/p>\n\n\n\n
Four precious coral species used in the jewellery trade are listed on Appendix III of CITES, and they require species-specific and country-of-origin documentation when being traded and transported across international borders. For the customs authorities that must check the merchandise, the colour of a coral specimen has to date been the main indicator for ascertaining its biological species identity. However, different coral species can have similar colour ranges, and this frequently has caused difficulties when trying to conclusively identify the specific species of coral contained in a jewellery item.<\/p>\n\n\n\n
The Coral-ID method was tested on a real-world set of samples, comprised of 20 coral-set items, seized between 2009 and 2017 by the Swiss customs authorities, because they lacked valid CITES documentation. Multiple species were found among corals of similar appearance, highlighting the importance of using the new forensic Coral-ID method, which is to avoid misidentification of CITES-listed species as non-CITES listed species, and vice versa.<\/p>\n\n\n\n
\u201cThe research shows the importance of carrying out fundamental science and peer-reviewed research on raw materials used in the jewellery industry. Genetic analysis of precious corals is clearly a very useful tool to achieve greater transparency in the trade,\u201d said Dr. Michael S. Krzemnicki, Director of SSEF.<\/p>\n\n\n\n
About the SSEF<\/p>\n\n\n\n
The Swiss Gemmological Institute SSEF, which is part of the Swiss Foundation for the Research of Gemstones (SSEF: Schweizerische Stiftung f\u00fcr Edelstein-Forschung), was founded by trade organisations in 1972 and works independently on a scientific basis. It is structured as a foundation under the aegis of Switzerland’s Federal Department of Home Affairs. The function of its laboratory is to analyse precious stones and issue test reports for diamonds, coloured stones and pearls. Members of SSEF Laboratory are also engaged in research and education, in connection with leading universities or with other gemmological laboratories.<\/p>\n","protected":false},"excerpt":{"rendered":"
