The paper reports and discusses data from archaeometric analyses and restoration intervention carried out on an assemblage of silver jewellery pieces from the Punic Southern necropolis of Tharros – Capo San Marco (Sardinia, Italy), a site whose relevance is primarily linked to its stratification, extending from the Nuragic age to the Middle Ages. Belonging to a funerary equipment from a primary incineration tomb, confidently ascribable to 7th-6th century BCE, the jewels were found in a precarious state of conservation, extremely fragmented and, in some cases, held together by a surface alteration layer. High-resolution X-rays CT allowed gaining insights into working techniques and decorative features of the finds under study, whose legibility was severely compromised by the alteration layer. OM and SEM-EDS analyses were also performed, to achieve a more exact characterisation of the alteration products. Obtained data allowed, on the one hand, to establish possible contact with North Africa and, on the other hand, to carry out a meticulous restoration intervention, fully respecting the original integrity of the artefacts despite the precarious state of conservation.
