This contribution aims to compare jewellery artefacts from some northern Italy archaeological sites, dated to different periods: the Copper age and Early Bronze age. Through a techno-typological and functional study that takes into account several morphometric, morphological and specific trace parameters (indicators of anthropic and/or wear activity), the methods, techniques and tools are reconstructed and compared. On one hand, with the typological analysis, jewellery has been looked at as a cultural marker allowing to gather information (raw material, forms, and measures) on different aspects of past life, such as style, territories, and traditions. On the other hand, with the technological analysis, interpretative hypotheses are proposed based on the comparison between production traces and experimental data, in order to reconstruct (in part or completely) manufacture procedures and fabrication techniques. Finally, a functional analysis enabled to distinguish wear traces from technological traces and to recognize if the object has been used or not.
