A recent preventive excavation on the site of “Lacoste” allowed the discovery, in contexts well dated, new fragments of glass ornaments. They enrich a collection mainly consisting of old pickups surface. So, therefore a corpus of 112 pieces of bracelets and beads is presented here. A quarter of them accurately reflect different phases of occupation of the site, between 220 and 80 a.C. Their study represents a significant complement to the documentation available in Gaul and issues related to chrono-typology and origins of these ornaments, typical of the period of La Tene C.
