For a little history on Etruscan jewelry.
During the Villanovan Era, there was very little jewelry which has remained for discovery in modern times. The Villanovan Etruscans seem to have had left few items of luxury and thus appear modest.
Gold jewelry started spreading rapidly during the Orientalizing era. This period was especially flourishing for Etruscan gold jewelry due to the very affluent trading system which had evolved during this time. The Etruscans did not invent their decorative techniques but borrowed from Mediterranean influences such as granulation. Syro-Phoenician jewelers settled in southern Etruria and taught local apprentices this art as well as filigree.
These techniques first developed in the South of Etruria. It consisted of working designs onto a surface with tiny granules of gold. Care had to be taken not to melt the little granules onto the surface but instead, to solder them on with a tiny heated point. The various omissions and imperfections, made on purpose, gave the piece of jewelry the artistic character. Soldering was done using (most likely) arseniates and reducing the solder to an impalpable dust.
Much of the jewelry found wasn’t worn by Etruscans, but were made to accompany them in the after world. Most, if not all, techniques of Etruscan goldsmiths were not invented by them as they are dated to the third millennium BC.
These practices came to them from the (at the time) distant Middle East, along with imported objects who inspired them to widen their range of jewelry. The Etruscans perfected these techniques, and in turn lead them to the very stylized jewelry of the seventh and sixth centuries. Often these pieces are considered the peak of their abilities.
