A bronze bracelet of the spiral type was found in the circular chamber well located in the courtyard of the Nuraghic complex La Prisgiona in the territory of Arzachena (fig. 1).

The object may be placed in the category of ornaments, rather rare in Nuraghic contexts known to date.

Very simple, it consists of a strip rolled up into four spirals (measurements: h. 6.8 cm; diam. 6.3 cm), whose ends are fragmentary (figs. 2, 3, 4), obtained by using the forging and cold hammering techniques.
