Recently, a necklace was submitted to SSEF for coral testing. Already a first microscopic inspection revealed that this item in fact consisted of numerous tiny glass beads, visually imitating coral very well (e.g. corallium rubrum). The most obvious microscopic feature was the presence of air bubbles in these g
In 2022, an international research group led by scientists from the Swiss Gemmological Institute SSEF and the University of Zurich’s Institute of Forensic Medicine (IRM) reported a breakthrough in precious coral jewellery traceability, through the use of a novel forensically validated genetic technique called

Pearl testing was long limited to determining whether a pearl is natural or cultured, and whether a pearl has been treated or not. As we have considerably invested in pearl research in recent years, we have achieved significant breakthroughs, namely DNA fingerprinting for species identification and radiocarbon
by Dr. M.S. Krzemnicki, first published in Facette 26 (May 2020) Since 2017, the Swiss Gemmological Institute SSEF offers radiocarbon dating of pearls as a service. To further expand our knowledge about this method and its applicability to other biogenic gem materials, we were happy to receive a number of smal
DNA fingerprinting of ivory involves a scientific method that can provide valuable information about the species of ivory being used in jewellery and ornamental objects, in order to determine whether it is CITES- listed elephant ivory or non-listed mammoth ivory. DNA fingerprinting, together with a morphologica
SSEF pioneered DNA fingerprinting of pearls in 2013, in collaboration with scientists from ETH Zürich. This was the first published report of oyster DNA extraction from a pearl, allowing us to trace and fingerprint pearls of unknown origin and match them to the specific oyster species in which they formed.
