Goods decorated in the Ring Decoration style are prevalent in Sambian-Natangian culture from the early phase of the Late Roman Period. Several types of adornment are known: with single or several hoops, and with a combination of wire and embossed foil. Ring Decoration types can be used as date markers, since they existed at fixed periods in time. Pieces decorated with rings can be assigned to the regions of the Vistula and the Baltic Sea islands, and can be considered evidence of contacts between the elites of Sambia, Scandinavia and Germania Libera.
