Modern and ancient gold jewellery attributed to the Etruscans: a science-based study

A fibula with a lion and a pair of cluster earrings from the collection of the Florence National Museum of Archaeology, attributed to the Etruscans and said to originate from Populonia but suspected to be modern productions, were studied in the framework of the European project AUTHENTICO. They were compared to genuine objects from this same collection and from the collection of the National Museums Scotland. The study was carried out in situ in Florence with a stereomicroscope equipped with a digital camera, a handheld XRF spectrometer, and the portable LIPS prototype developed by AUTHENTICO. Some objects were studied with SEM and X-radiography. The aim of the study was to show that portable techniques of examination and analysis provide information on gold jewellery that allow the differentiation of modern and ancient productions.
