During the 3rd century BC and mainly during Late Antiquity, the material commonly known as « jet » was used among others to make small black and shiny artifacts in the north-western provinces of the Roman Empire. This production mainly concerns personal objects: adornments (bracelets, hairpins, necklace beads, pendant medallions, finger rings, etc.), but also game pieces (dices and pawns), various utensils (knife handles, spindle whorls) or small containers (jewelry boxes, pyxis, box decorations). Following particularly the development of preventive archaeology, since the 1990s, jet pieces have been found in domestic, funerary and religious contexts. Based on updated occurrences, mainly from Gaul, Germania and Britannia, this article aims to provide the distribution of this kind of artifacts in the North-west of the Roman Empire during the Late Antiquity.
