The making of ornaments is one of the industries that has always been considered in ancient Iran. Among the outstanding works in this field are the golden collars belonging to the Sassanid and Parthian periods of the Reza Abbasi Museum. These golden collars have special structural features and decorative methods that by studying them, in addition to showing the historical course of making the collar, their special decorations will also be introduced.The main focus of this research is the structural form of the two samples studied and the decorations of each work. Accordingly, first the structural and decorative features of each work have been studied separately, then the collars have been studied comparatively.The results of this study introduce the techniques used in these works and also show the commonalities and differences in the collar making of these two periods, so that it can be said that these two collars have many similarities in terms of structure and decoration method. It shows the continued use of popular artistic traditions for several centuries.
